CHAPTER 1 INTRODUCTION
1.1 ABOUT THE PROJECT
Online Examination helps the students for appearing the exam by online. Its mission is to offer a quick and easy way to appear the exam and it also provide the result immediately after the exam. Through partnerships with agencies\boards which are conducting the multiple choice type examination, it can provide special advantages to the applicants/students that can't be found anywhere else.
The working of the project is as follows.
The first page provides several links. The Home link contains several informations about online examination; it provides a link to the login page.
In the Login link a user have to login before entering for the exam. An already registered user can simply type in his\her valid username and password, and then click the "Login" button. Already registered user can only register a new user as a teacher. But those visitors who are not registered have to go to the registration page for registering only as a student before they login. In that page user have to enter Name, Address, Phone number, Role id and password; and also the user have to update the photo.
About Link contains some information regarding Online Examination and its developers.
After registration, if the user registered as a teacher can create the question and can conducting the exam can also publishing the results and reports. Otherwise the user registered as a student and he/she can answer the exam. The Login page contains several links according to whether the user is student or teacher.
If the user is a teacher, then he/she can create question paper. This is provided by Create Question Paper Link. In that page user have to enter Exam ID, No: of Series, No: of questions, No: of Options, Total time (in min), Marks per Question, Negative mark, Examination Password, Option type. Then go to the question paper page. In that page user have to enter the questions and options and the right answer. The Link Question Paper Preview shows already created question paper.
If the user is a student, can answer the exam. This is provided by the Link Examination. The Link Rules and Regulations show some rules and regulations that should be followed by the user.

CHAPTER 2
PROBLEM DEFINITION
Online Examination is very helpful to users. The aim of this project is to provide quick, immediate and easy way to appear the exam. It can provide special advantages to the students/applicants that can't be found anywhere else through partnerships with agencies/boards that are conducting the multiple choice type examination. Its working is that students allows registering for the exam and teacher allows registering for conducting the exam. This will continue to grow - ultimately providing a wide breadth of services for beneficial to the students.
Online examination questions can be categorized according to topic, types, etc. (libraries) .The online examination system makes provision for difficulty levels of items. A test can be compiled with questions from different topics/libraries. A "serial number" is provided for each question according to topic, etc. Questions can be converted to the databank from existing databanks. Tests can be created on a random basis per student. The online examination system can automatically add the marks allocated in each question to determine the total mark for the test. Different papers (shuffle code) and memoranda can be compiled.A time limit can be set for the test. The sequence of questions can be randomized. Online Examination System allows jumping to specific questions based on the previous answer. The options per question can be randomized. The online examination system limits the number of times a student can write a test. Students can be forced to go through all the questions at least once, before exiting the test. Students can be allowed to exit the test before completing all the questions.
Login module helps the user to login to the site. For that he/she must type the username and password correctly. The login provision in this page helps the already registered user to directly access the site and there is a link for registration to a user who is new to this site.
Student module is mainly for the students. This helps the students to register for the exam and answer the exam. For registration name, address, phone no, role id, password should be entered. This will provide immediate result after the exam according to correct and wrong answer.
Administrator module is mainly for the administrator. This will contain the creation of question paper, preview of already created question paper, and the report of the administrator. For creating the question paper he/she must enter Exam ID, No: of Series, No: of questions, No: of Options, Total time (in min), Marks per Question, Negative mark, Examination Password, Option type. For showing the preview of already created question paper he/she must enter the correct Exam id.
2.1 EXISTING SYSTEM
The existing system is manual entry of up keeping of the details of the persons who are registered already. And it is very difficult for each person to come to the exam center. It is very difficult to the students from far distance to reach the exam center. This system is required to prepare registration\application form, question paper for the students and required to print a lot of number manually. To calculate how many students registered, and verification of details of these students in a month by hand is very difficult. This requires quite a lot of time and wastage of money as it requires quite lot of manpower to do that. Another factor that takes into account that is the possibility of errors and which requires verification and checking of data relating to various operations which is done manually. The limitation of existing system is that it is not all personalized. It cannot be used for personal and quick reference. Even the other staff members can make quick entries if the responsible person is not present.
2.2 PROPOSED SYSTEM
The modern computerized system is developed with the aim to overcome the drawbacks of existing system. The proposed system has got many advantages. People from different parts of the world can register very easily. The new system is more personalized. It is maze in such a manner that all the new users can understand all the options in it very easily. It is made in a quick and easy referential manner.
Access to all important matters are not always locked and can be opened easily at the time of urgency. The advantages of proposed system are that security is maintained in the new system. Securities for all important data are maintained confidentially. As it is easily understandable and user friendly, quick entries can be made in this system.
CHAPTER 3 SYSTEM STUDY
The system study phase involves the initial investigation of the structure of the System, which is currently in use, with the objective of identifying the problem and difficulties with the existing system. The major steps involved in this phase included defining the user requirements and studying the present system to verify the problem. The performance expected by the new system was also defined in this phase in order to meet the user requirements. The information gathered from various documents were analyzed and evaluated and the findings reviewed in order to establish specific system objectives.
3.1 SYSTEM ANALYSIS
System analysis is the way of studying a system with an eye on solving its problem using computer. It is the most essential part of the development of a project of a system analysis. System analysis consists of system element, process and technology.
To analyze a system, has to study the systems in details. The analyst has to understand the functioning and concept of the system in detail, before design the appropriate computer based system that will meet all the requirements of the existing system. The system analyst has to carry out a customary approach to use the computer for problem solving.
System analysis includes the following basic concepts
¢ Preliminary investigation
¢ Requirements specification
¢ Feasibility study
¢ Detailed investigation
¢ Drawing up of strategies
¢ Design and coding
¢ Testing and training
¢ Implementation
The above steps constitute the logical framework for the system analysis. After the preliminary investigation and feasibility study, the scope of the defined and comparable items are set forth and hence detailed investigation is executed. This allows the system analyst to comprehend the full scope of the project. Soon after the implementation of the newly developed system, followed by the training of the users, the system analysis is included.
CHAPTER 4 PRELIMINARY INVESTIGATION
A request to receive assistance from information system can be made for many reasons, but in case a manager, employee or system specialist initiates the request. When that request is made, the first system activity preliminary investigation begins. The activity has three parts
> Request clarification: the request from employee may not be well stated. Sometimes the request may not be well defined. Therefore before any system investigation can be considered, the project request must be examined to determine precisely the actual requirements of the organization.
> Feasibility study: the basic idea of feasibility study is to determine whether the requested project is feasible.
> Request approval: all projects that are requested are not desirable or feasible .some organization receive so many projects requests from employee that only a few of them can be pursued. However those projects that are feasible and desirable should put into a schedule. The management decides request that are most important. After a project request is approved the cost priority, the completion time and the personal required are estimated. Once the request is approved, the collection of data and determination of requirements can be started.
CHAPTER 5 REQUIREMENT SPECIFICATION
The primary goal of the system analyst is to improve the efficiency of the existing system. For that the study of specification of the requirements is very essential. For the development of the new system, a preliminary survey of the existing system will be conducted. Investigation done whether the upgradation of the system into an application program could solve the problems and eradicate the inefficiency of the existing system.
5.1 FEASIBILITY STUDY
The initial investigation poi nts to the question whether the project is feasible. A feasibility is conducted to identify the best system that meets the all the requirements. This includes an identification description, an evaluation of the proposed systems and selection of the best system for the job
The requirements of the system are specified with a set of constraints such as system objectives and the description of the out puts. It is then duty of the analyst to evaluate the feasibility of the proposed system to generate the above results. Three key factors are to be considered during the feasibility study.
5.1.1 Operation Feasibility
An estimate should be made to determine how much effort and care will go into the developing of the system including the training to be given to the user. Usually, people are reluctant to changes that come in their progression. The computer initialization will certainly affected the turn over, transfer and employee job status. Hence an additional effort is to be made to train and educate the users on the new way of the system.
5.1.2 Technical Feasibility
The main consideration is to be given to the study of available resources of the organization where the software is to be implemented. Here the system analyst evaluates the technical merits of the system giving emphasis on the performance, reliability, maintainability.
By taking the consideration before developing the proposed system, the resources availability of the organization was studied. The organization was immense computer facilities equipped with sophisticated machines and the software hence this technically feasible.
5.1.3 Economic Feasibility
Economic feasibility is the most important and frequently used method for evaluating the effectiveness of the proposed system. It is very essential because the main goal of the proposed system is to have economically better result along with increased efficiency. Cost benefit analysis is usually performed for this purpose. It is the comparative study of the cost verses the benefit and savings that are expected from the proposed system. Since the organization is well equipped with the required hard ware, the project was found to be economically.

5.4 TECHNOLOGY SPECIFICATION
o Client-Server Architecture
Typical client-server systems are based on the 2-tiered architecture, whereby there is a clear separation between the data and the presentation/business logic. These are generally data driven, with the application existing entirely on the client machine while the database server is deployed somewhere in the organization.
o 2-Tier Architecture
In a traditional 2- Tiered application, the processing load is given to the client PC while the server simply acts as a traffic controller between the application and data. As a result, not only does the application performance suffer due to the limited resources of the PC, but the network traffic tends increase as well.
o 3- Tier Architecture
In 3- Tier architecture an application is broken into three separate logical layers, each with a well defined set of interfaces. The first tier is referred to as the presentation layer and typically consists of graphical user interface of some kind. The middle tier, or business layer, consists of application or business layer and the third layer- the data layer contains the data that is needed for the application. The middle tier is basically the code that the user calls upon to retrieve the desired data. The presentation layer then receives the data and formats it for display. This separation of application logic from the user interface adds enormous flexibility to the design of application. The third tier contains the data that is needed for the application.
o n- Tier Architecture
Inann - tier architecture the application logic is divided by function rather than physically. N - Tier architecture then breaks down like this:
> A user interface that handle the user's interaction with the application; this can be web browser running through a firewall, a heavier desktop application or even a wireless device
> Presentation logic that defines what the user interface displays and how a user's requests are handled- depending on what user interfaces are supported we need to have slightly different versions of the presentation logic to handle the client appropriately.
> Business logic that models the application's business rules, often through the interaction with the application's data.
> Interface services that provide additional functionality required by the application components, such as messaging, transactional support etc.
> The Data layer where the enterprise's data resides.
CHAPTER 6 SYSTEM DESIGN
System design is the solution to the creation of a new system. This phase is composed of several systems. This phase focuses on the detailed implementation of the feasible system. It emphasis on translating design specifications to performance specification. System design has two phases of development logical and physical design.
During logical design phase the analyst describes inputs (sources), out puts (destinations), databases (data sores) and procedures (data flows) all in a format that meats the uses requirements. The analyst also specifies the user needs and at a level that virtually determines the information flow into and out of the system and the data resources. Here the logical design is done through data flow diagrams and database design.
The physical design is followed by physical design or coding. Physical design produces the working system by defining the design specifications, which tell the programmers exactly what the candidate system must do. The programmers write the necessary programs that accept input from the user, perform necessary processing on accepted data through call and produce the required report on a hard copy or display it on the screen.
6.1 LOGICAL DESIGN
Logical design of an information system shows the major features and also how they are related to one another. The first step of the system design is to design logical design elements. This is the most creative and challenging phase and important too. Design of proposed system produces the details of the state how the system will meet the requirements identified during the system analysis that is, in the design phase we have to find how to solve the difficulties faced by the existing system. The logical design of the proposed system should include the details that contain how the solutions can be implemented. It also specifies how the database is to be built for storing and retrieving data, what kind of reports are to be created and what are the inputs to be given to the system. The logical design includes input design, output design, and database design and physical design
6.2 INPUT DESIGN
The input design is the link between the information system and the user. It comprises the developing specification and procedures for data preparation and those steps are necessary to put transaction data into a usable form for processing data entry. The activity of putting data into the computer for processing can be achieved by inspecting the computer to read data from a written or printed document or it can occur by having people keying the data directly into the system.
The system needs the data regarding the asset items, depreciation rates, asset transfer, physical verification for various validation, checking, calculation and report generation.. The error raising method is also included in the software, which helps to raise error message while wrong entry of input is done. So in input design the following things are considered.
What data should be given as input
¢ How the data should be arranged or coded
¢ The dialogue to guide the operating personnel in providing input.
¢ Methods for preparing input validations and steps to follow when error occur
¢ The samples of screen layout are given in the appendix.
6.3 OUTPUT DESIGN
Computer output is the most important and direct information source to the user. Output design is a process that involves designing necessary outputs in the form of reports that should be given to the users according to the requirements. Efficient, intelligible output design should improve the system's relationship with the user and help in decision making. Since the reports are directing referred by the management for taking decisions and to draw conclusions they must be designed with almost care and the details in the reports must be simple, descriptive and clear to the user.
¢ Determine what information to present
¢ Arrange the presentation of information in an acceptable format
¢ Decide how to distribute the output to intended receipts
Depending on the nature and future use of output required, they can be displayed on the monitor for immediate need and for obtaining the hardcopy. The options for the output reports are given in the appendix.
6.4 PHYSICAL DESIGN
The process of developing the program software is referred to as physical design. We have to design the process by identifying reports and the other outputs the system will produce. Coding the program for each module with its logic is performed in this step. Proper software specification is also done in this step.
6.5 MODULAR DESIGN
A software system is always divided into several sub systems that makes it easier for the development. A software system that is structured into several subsystems makes it easy for the development and testing. The different subsystems are known as the modules and the process of dividing an entire system into subsystems is known as modularization or decomposition.
A system cannot be decomposed into several subsystems in any way. There must some logical barrier, which facilitates the separation of each module. The separation must be simple but yet must be effective so that the development is not affected.
The system under consideration has been divided into several modules taking in consideration the above-mentioned criteria. The different modules are
1) Login Module
2) Registration Module.
3) Question paper creation Module.
4) Examination Module.
5) Student Module.
6) Administrator Module.
CHAPTER 7 DATABASE DESIGN
The overall objective in the development of database technology has been to treat data as an organizational resource and as an integrated whole. DBMS allow data to be protected and organized separately from other resources. Database is an integrated collection of data. The most significant form of data as seen by the programmers is data as stored on the direct access storage devices. This is the difference between logical and physical data.
Database files are the key source of information into the system. It is the process of designing database files, which are the key source of information to the system. The files should be properly designed and planned for collection, accumulation, editing and retrieving the required information.
The organization of data in database aims to achieve three major objectives: -
¢ Data integration.
¢ Data integrity.
¢ Data independence.
The proposed system stores the information relevant for processing in the MS SQL SERVER database. This database contains tables, where each table corresponds to one particular type of information. Each piece of information in table is called a field or column. A table also contains records, which is a set of fields. All records in a table have the same set of fields with different information. There are primary key fields that uniquely identify a record in a table. There are also fields that contain primary key from another table called foreign keys.
7.1 NORMALIZATION
Normalization is a technique of separating redundant fields and braking up a large table in to a smaller one. It is also used to avoid insertion, deletion and updating anomalies. All the tables have been normalized up to the third normal form. In short the rules for each of the three normal forms are as below.
¢ First normal form
A relation is said to be in 1NF if all the under lying domain of attributes contain simple individual values.
¢ Second normal form
The 2NF is based on the concept of full functional dependency. A relation said to be in 2NF if and only if it is in 1NF and every non-key attribute is fully functionally dependent on candidate key of the table.
¢ Third normal form
The 3NF is based on the concept of transitive dependency. A relation in 2NF is said to be in 3NF if every non-key attribute is non-transitively.
CHAPTER 8 SYSTEM IMPLEMENTATION
Implementation includes all those activities that take place to convert from the old system to the new. The old system consists of manual operations, which is operated in a very different manner from the proposed new system. A proper implementation is essential to provide a reliable system to meet the requirements of the organizations. An improper installation may affect the success of the computerized system.
8.1 IMPLEMENTATION METHODS:
There are several methods for handling the implementation and the consequent conversion from the old to the new computerized system.
The most secure method for conversion from the old system to the new system is to run the old and new system in parallel. In this approach, a person may operate in the manual older processing system as well as start operating the new computerized system. This method offers high security, because even if there is a flaw in the computerized system, we can depend upon the manual system. However, the cost for maintaining two systems in parallel is very high. This outweighs its benefits.
Another commonly method is a direct cut over from the existing manual system to the computerized system. The change may be with in a week or with in a day. There are no parallel activities. However, there is no remedy in case of a problem. This strategy requires careful
planning.
A working version of the system can also be implemented in one part of the organization and the personnel will be piloting the system and changes can be made as and when required. But this method is less preferable due to the loss of entirety of the system.
8.2 IMPLEMENTATION PLAN:
The implementation plan includes a description of all the activities that must occur to implement the new system and to put it into operation. It identifies the personnel responsible for the activities and prepares a time chart for implementing the system. The implementation plan consists of the following steps.
o List all files required for implementation.
o Identify all data required to build new files during the implementation. o List all new documents and procedures that go into the new system.
The implementation plan should anticipate possible problems and must be able to deal with them. The usual problems may be missing documents; mixed data formats between current and files, errors in data translation, missing data etc.
CHAPTER 9 EDUCATION AND TRAINING
The implementation of the proposed system includes the training of system operators. Training the system operators includes not only instructions in how to use the equipment, but also in how to diagnose malfunctions and in what steps to take when they occur. So proper training should be provided to the system operators. No training is complete without familiarizing users with simple system maintenance activities. Since the proposed system is developed in a GUI, training will be comparatively easy than systems developed in a non-GUI. There are different types of training. We can select off-site to give depth knowledge to the system operators.
Success of the system depends on the way in which it is operated and used. Therefore the quality of training given to the operating person affects the successful implementation of the system. The training must ensure that the person can handle all the possible operations.
Training must also include data entry personnel. They must also be given training for the installation of new hardware, terminals, how to power the system, how to power it down, how to detect the malfunctions, how to solve the problems etc. the operators must also be provided with the knowledge of trouble shooting which involves the determination of the cause of the problem.
The proposed system requires trained personnel for operating the system. Data entry jobs must be done utmost carefully to avoid errors. This will reduce the data entry errors considerably. It is preferable to provide the person with some kind of operating manuals that will explain all the details of the system.
9.1 POST IMPLEMENTATION REVIEW
After the system is implemented, a review should be conducted to determine whether the system is meeting expectations and where improvements are needed. System quality, user confidence and operating systems statistics are accessed through such technique event logging, impact evaluation and attitude surveys. The review not only assesses how well the proposed system is designed and implemented, but also is a valuable source of information that can be applied to a critical evaluation of the system.
The reviews are conducted by the operating personals as well as the software developers in order to determine how well the system is working, how it has been accepted and whether adjustments are needed. The review of the system is highly essential to determine the future enhancements required by the system. The system can be considered successful only if information system has met it objectives. The review analyses the opinion of the employees and identifies the attitudes towards the new computerized system. Only when the merits and demerits of the implemented system are known, one can determine what all additional features it requires are. The following are the issues to be considered in the evaluation of the system.
CHAPTER 10 SYSTEM TESTING
System testing is a critical aspect of Software Quality Assurance and represents the ultimate review of specification, design and coding. Testing is a process of executing a program with the intent of finding an error. A good test is one that has a probability of finding an as yet undiscovered error. The purpose of testing is to identify and correct bugs in the developed system. Nothing is complete without testing. Testing is the vital to the success of the system.
In the code testing the logic of the developed system is tested. For this every module of the program is executed to find an error. To perform specification test, the examination of the specifications stating what the program should do and how it should perform under various conditions.
Unit testing focuses first on the modules in the proposed system to locate errors. This enables to detect errors in the coding and logic that are contained within that module alone. Those resulting from the interaction between modules are initially avoided. In unit testing step each module has to be checked separately.
System testing does not test the software as a whole, but rather than integration of each module in the system. The primary concern is the compatibility of individual modules. One has to find areas where modules have been designed with different specifications of data lengths, type and data element name.
Testing and validation are the most important steps after the implementation of the developed system. The system testing is performed to ensure that there are no errors in the implemented system. The software must be executed several times in order to find out the errors in the different modules of the system.
Validation refers to the process of using the new software for the developed system in a live environment i.e., new software inside the organization, in order to find out the errors.
The validation phase reveals the failures and the bugs in the developed system. It will be come to know about the practical difficulties the system faces when operated in the true environment. By testing the code of the implemented software, the logic of the program can be examined. A specification test is conducted to check whether the specifications stating the program are performing under various conditions. Apart from these tests, there are some special tests conducted which are given below:
Peak Load Tests: This determines whether the new system will handle the volume of activities when the system is at the peak of its processing demand. The test has revealed that the new software for the agency is capable of handling the demands at the peak time.
Storage Testing: This determines the capacity of the new system to store transaction data on a disk or on other files. The proposed software has the required storage space available, because of the use of a number of hard disks.
Performance Time Testing: This test determines the length of the time used by the system to process transaction data.
In this phase the software developed Testing is exercising the software to uncover errors and ensure the system meets defined requirements. Testing may be done at 4 levels
¢ Unit Level
¢ Module Level
¢ Integration & System
¢ Regression
10.1 UNIT TESTING
A Unit corresponds to a screen /form in the package. Unit testing focuses on verification of the corresponding class or Screen. This testing includes testing of control paths, interfaces, local data structures, logical decisions, boundary conditions, and error handling. Unit testing may use Test Drivers, which are control programs to co-ordinate test case inputs and outputs, and Test stubs, which replace low-level modules. A stub is a dummy subprogram.
10.2 MODULE LEVEL TESTING
Module Testing is done using the test cases prepared earlier. Module is defined during the time of design.
10.3 INTEGRATION & SYSTEM TESTING
Integration testing is used to verify the combining of the software modules. Integration testing addresses the issues associated with the dual problems of verification and program construction. System testing is used to verify, whether the developed system meets the requirements.
10.4 REGRESSION TESTING
Each modification in software impacts unmodified areas, which results serious injuries to that software. So the process of re-testing for rectification of errors due to modification is known as regression testing. Installation and Delivery
Installation and Delivery is the process of delivering the developed and tested software to the customer. Refer the support procedures Acceptance and Project Closure
Acceptance is the part of the project by which the customer accepts the product. This will be done as per the Project Closure, once the customer accepts the product; closure of the project is started. This includes metrics collection, PCD, etc.
CHAPTER 11 MAINTENANCE
Maintenance is making adaptation of the software for external changes (requirements changes or enhancements) and internal changes (fixing bugs). When changes are made during the maintenance phase all preceding steps of the model must be revisited.
There are three types of maintenance:
1. Corrective (Fixing bugs/errors)
2. Adaptive (Updates due to environment changes)
3. Perfective (Enhancements, requirements changes)

APPENDICES
OVERVIEW OF J2EE
Today, more and more developers want to write distributed transactional applications for the enterprise and leverage the speed, security, and reliability of server-side technology. If you are already working in this area, you know that in today's fast-moving and demanding world of e-commerce and information technology, enterprise applications have to be designed, built, and produced for less money, with greater speed, and with fewer resources than ever before.
To reduce costs and fast-track enterprise application design and development, the Java „¢ 2 Platform, Enterprise Edition (J2EE„¢) technology provides a component-based approach to the design, development, assembly, and deployment of enterprise applications. The J2EE platform offers a multitiered distributed application model, the ability to reuse components, integrated Extensible Markup Language (XML)-based data interchange, a unified security model, and flexible transaction control. Not only can you deliver innovative customer solutions to market faster than ever, but your platform-independent J2EE component-based solutions are not tied to the products and application programming interfaces (APIs) of any one vendor. Vendors and customers enjoy the freedom to choose the products and components that best meet their business and technological requirements.
JAVA SERVER PAGES (JSP)
The Java 2 Enterprise Edition (J2EE) has taken the once-chaotic task of building an Internet presence and transformed it to the point where developers can use Java to efficiently create multi-tier, server-side applications. Today, the Java Enterprise APIs have expanded to encompass a number of areas: RMI and CORBA for remote object handling, JDBC for database interaction, JNDI for accessing naming and directory services, Enterprise Java Beans for creating reusable business components, JMS (Java Messaging Service) for message oriented middleware, JAXP for XML processing, and JTA (Java Transaction API) for performing atomic
64
transactions. In addition, J2EE also supports Servlets, an extremely popular Java substitute for CGI scripts. The combination of these technologies allows programmers to create distributed business solutions for a variety of tasks. In late 1999, Sun Microsystems added a new element to the collection of Enterprise Java tools: Java Server Pages (JSP). Java Server Pages are built on top of Java Servlets and are designed to increase the efficiency in which programmers, and even nonprogrammers, can create web content.
> Area of Java Server Pages
Put succinctly, Java Server Pages is a technology for developing web pages that include dynamic content. Unlike a plain HTML page, which contains static content that always remains the same, a JSP page can change its content based on any number of variable items, including the identity of the user, the user's browser type, information provided by the user, and selections made by the user. This functionality is key to web applications such as online shopping and employee directories, as well as for personalized and internationalized content. A JSP page contains standard markup language elements, such as HTML tags, just like a regular web page. However, a JSP page also contains special JSP elements that allow the server to insert dynamic content in the page. JSP elements can be used for a variety of purposes, such as retrieving information from a database or registering user preferences. When a user asks for a JSP page, the server executes the JSP elements, merges the results with the static parts of the page, and sends the dynamically composed page back to the browser.
JSP defines a number of standard elements that are useful for any web application, such
as accessing Java Beans components, passing control between pages and sharing information
Programmers can also extend the JSP syntax by implementing application-specific elements that
perform tasks such as accessing databases and Enterprise Java Beans, sending email, and
generating HTML to present application-specific data. One such set of commonly needed custom
elements is defined by a specification related to the JSP specification: the JSP Standard Tag
Library (JSTL) specification. The combination of standard elements and custom elements allows
for the creation of powerful web applications.
Use of JSP
In the early days of the Web, the Common Gateway Interface (CGI) was the only tool for developing dynamic web content. However, CGI is not an efficient solution. For every request that comes in, the web server has to create a new operating-system process, load an interpreter and a script, execute the script, and then tear it all down again. This is very taxing for the server and doesn't scale well when the amount of traffic increases.
Numerous CGI alternatives and enhancements, such as FastCGI, mod_perl from Apache, NSAPI from Netscape, ISAPI from Microsoft, and Java Servlets from Sun Microsystems, have been created over the years. While these solutions offer better performance and scalability, all these technologies suffer from a common problem: they generate web pages by embedding HTML directly in programming language code. This pushes the creation of dynamic web pages exclusively into the realm of programmers. Java Server Pages, however, changes all that.
> Oracle 9i
An Oracle database comprises instance and data storage. The instance comprises a set of operating system processes and memory structures that interact with the storage. Typical processes include PMON (the process monitor) and SMON (the system monitor).
Oracle users refer to the server-side memory-structure as the SGA (System Global Area). The SGA typically holds cache information like data-buffers, SQL commands and user information. In addition to storage, the database consists of online redo logs (which hold transactional history). Processes can in turn archive the online redo logs into archive logs (offline redo logs), which provide the basis (if necessary) for data recovery and for some forms of data replication.
The Oracle RDBMS stores data logically in the form of tablespaces and physically in the form of data files. Tablespaces can contain various types of segments, for example, Data Segments, Index Segments etc. Segments in turn comprise one or more extents. Extents comprise groups of contiguous data blocks. Data blocks form the basic units of data storage. Oracle keeps track of its data storage with the help of information stored in the SYSTEM tablespace.
66
The SYSTEM tablespace contains the data dictionary - and often (by default) indexes and clusters. (A data dictionary consists of a special collection of tables that contains information about all user objects in the database). Since version 8i, the Oracle RDBMS also supports "locally managed" tablespaces, which can store space management information in bitmaps in their own headers rather than in the SYSTEM tablespace (as happens with the default "dictionary-managed" tablespaces).
The Oracle DBMS can store and execute stored procedures and functions within it. PL/SQL (Oracle Corporation's proprietary procedural extension to SQL), or the object-oriented language Java can invoke such code objects and/or provide the programming structures for writing them.
RESUME
The developed system is flexible and changes can be made easily. The system is developed with an insight into the necessary modification that may be required in the future. Hence the system can be maintained successfully without much rework.
One of the main future enhancements of our system is to add a mail response from the administrator to the user. So that the user can understand whether he/she is eligible for appearing the exam, directly from the administrator.

ABSTRACT


Online Examination System is aimed at computerizing the activities involved in Examination. The primary activities in the exam include importing the question paper, generating the reports and taking the backup.

This project includes the following Modules:


1. Administrator module

This module deals with the Question paper importing, Student list importing, Student userid and password generation, Report generation, User blocking and Unblocking and taking the backup.


2. Student Module


This module deals with the student logging into the system and taking the exam.


INTRODUCTION

This is the project work undertaken in context of partial fulfillment of Diploma in Advance Computing. We have tried our best to make the Online Examination Software system as simple as possible using structured, modular & with better user interface. This project is used by two types of users:

i. Students.
ii. Administrator.

The student can login into the system with the userid given to him by the administrator to take up the exam. He is provided with the question and choices through which he can select the answers for each question. He is able to move back to the previous question and can change the previously selected answers.

The administrator can import the question paper, import the student list and generate the userid & password, generate the reports and take printouts. Administrator can generate the marks report of the particular user. Administrator can generate the rules & instructions for each exam.The administrator can also set the time for each examination. Administrator is able to take the backup of the question paper and also the details of the student
