Examination Management System – VB 6.0
Introduction to Purpose System (Examination Management System) Examination Management System is a software developed for the students who give exams in colleges and institutes. It facilitates to access the examination information of a particular student in a particular class. The information is sorted by the operators, which will be provided by the teacher for a particular class. This system will also help in evaluating examination eligibility criteria of a student. The purpose of developing examination management system is to computerized the traditional way of taking exams. Another purpose for developing this software is to generate the report automatically about the sitting arrangement during exams at the end of the session or in the between of the session. The scope of the project is the system on which the software is installed, i.e. the project is developed as a desktop application, and it will work for a particular institute. But later on the project can be modified to operate it online. Examination Management System basically has two main modules for proper functioning
First module is admin which has right for creating new examination cell for new batch and update student results.
Second module is handled by the user which can be a faulty or an operator. User has a right to see the results.
The main purpose of the online examination program is that it allows companies/institutions to perform examinations to any number of applicants at once, in a computerized manner. It decreases
enough time intake and amount of work that exist in the current program of
evaluation. It also allows in saving the record of each evaluation and the results are also saved in the program. This makes the seeking of the information easier than the current program. Examination Management System is very useful for Educational Institute to prepare an exam, safe the time that will take to check the paper and prepare mark sheets. It will help the Institute to

Examination Management System – VB 6.0 testing of students and develop their skills. But the disadvantages for this system, it takes a lot of times when you prepare the exam at the first time for usage. And we are needs number of computers with the same number of students. The effective use of "Examination Management System", any Educational Institute or training centers can be use it to develop their strategy for putting the exams, and for getting better results in less time.

Objectives Of the Project The primary objective of the program is to effectively assess the applicant thoroughly through a completely automated system that not only helps you to save a lot of time but also gives quick outcomes. It is a cost-effective and well-known indicates of mass- assessment program. Corporate between the data stored in the server of the Institution and our On-line Exam system. To deal with On-line System in an easy way and an efficient mannered. (connection process) Create strong and secrete data base that allow for any connection in a secret way, to prevent any outside or inside attacks. Specify a privilege for each person to allow each person use this system to create his own exam. And have a complete control on his exam. Allow each person to create more than one exam with different way to create variant questions.
Scope and limitations:
Examination Management system is designed for Educational Institutes (like schools, universities, training centers).
The system handles all the operations, and generates reports as soon as the test is finish, that includes name, mark, time spent to solve the exam.
Allow students to see or display his answers after the exam is finish.
The type of questions is only multiple choice or true and false.

SYSTEM ANALYSIS 2.1 Existing system The Existing system of conducting examination process is manual. It has so many problems. So we introduce a new system, which is fully computerized. Existing system is a large man power process and is difficult to implement. Working of existing system is given below: Student Registration is the first process . As the part of the registration, the student has to enter his name, address etc into the registration form. After the registration, make the question papers and it will give to the prospective student. The question papers contain total mark, subject, duration, questionpaper
etc.
A group of person does evaluation of answer sheet. After the evaluation of the Answer sheet , the result is published. And also make the mark list.
2.2 Proposed system The
main
objective
of
the
online
examination
system
is
that
it
helps
companies/institutions to conduct exams to any number of candidates at a time, in an automated manner. It reduces the time consumption and workload that exist in the current system of examination. It also helps in storing the record of each examination and the results are also stored in the system. This makes the searching of the records easier than the existing system.
2.3 Objectives of the proposed system The main purpose of the system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves a lot of time but also gives fast results. It is a cost-effective and popular means of mass- evaluation system. The administrator of the system prepares the tests and questions for each exam. The candidates can login through the client computers with their register number given to them and can take the exam. The questions are shuffled in a random order so that possibilities for getting questions in the same order for the students who are sitting near, is very less. A timer will
- (5) -
Examination Management System – VB 6.0 monitor the time and after the time limit the system itself submit the test. If it is before time, candidates can submit it to view their result. The result analysis is very easy as it is done by the system. So it saves a lot of time since no manual correction is needed in the system. No restriction is there that the invigilator has to be present when the students take the test. 2.4 Feasibility study Feasibility is a measure of how beneficial the development of the information system will be to an organization. This is done by investigating the existing system in the area under investigation or generally ideas about a new system. It is a test of a system proposal according to its workability, impact on the organization, ability to meet user needs, and effective use of resources. Three key considerations are involved in the feasibility analysis: economic, technical, and legal.
Economic feasibility: Economic analysis is the most frequently used method for evaluating the effectiveness of a proposed system. It is more commonly known as cost benefit analysis, the procedure to determine the benefits and saving that are expected from a candidate system and compare them with costs. If the benefits outweigh costs then a decision is made to design and implement the system. Otherwise make alterations in the proposed system. The innovation of the new system has much influence on the economical side of the company. Manuel system is highly cost driven due to the high labor costs. So if a company registers with the Online_Examination site, they can automate their day-to-day activities. Thus the system is economically feasible. Technical feasibility: In examining Technical feasibility of the system, more importance is given to the hardware interaction part of the system. The assessments of technical feasibility centers on the existing system and to what extent it can support the proposed addition. This was based on an outline design of system requirements in turns of inputs, files, programs, procedures, and staff. It
- (6) -
Examination Management System – VB 6.0 involves financial considerations to accommodate technical enhancements. Online_Examination being a web based application, it uses .Net framework, 800MHZ computer, 20 GB Hard disk. Legal feasibility: People are inherently resistant to change, and computers have been known to facilitate change. An estimate should be made about the reaction of the user staff towards the development of a computerized system. Computer installations have something to do with turnover, transfers and changes in job status. The introduction of a candidate system requires special effort to educate, sell and train the staff for conducting the business. The system is designed such that even a computer ignorant person can interact with the system freely. So the system requires not much effort to train and educate people, the system is that much legally feasible.

Examination Management System – VB 6.0 Feasibility Study: After doing the system study and analyzing all the existing or required functionalities of the system, the next task is to do the feasibility study for the project. All projects are feasible - given unlimited resources and infinite time. Feasibility study includes consideration of all the possible ways to provide a solution to the given problem. The proposed solution should satisfy all the user requirements and should be flexible enough so that future changes can be easily done based on the future upcoming requirements. A. Economical Feasibility
This is a very important aspect to be considered while developing a project. We decided the technology based on minimum possible cost factor. All hardware and software cost has to be borne by the organization. Overall we have estimated that the benefits the organization is going to receive from the proposed system will surely overcome the initial costs and the later on running cost for system. B. Technical Feasibility This included the study of function, performance and constraints that may affect the ability to achieve an acceptable system. For this feasibility study, we studied complete functionality to be provided in the system, as described in the System Requirement Specification (SRS), and checked if everything was possible using Visual Basic 6.0 and MS Access. C. Operational Feasibility No doubt the proposed system is fully GUI based that is very user friendly and all inputs to be taken all self-explanatory even to a layman. Besides, a proper training has been conducted to let know the essence of the system to the users so that they feel comfortable with new system. As far our study is concerned the clients are comfortable and happy as the system has cut down their loads and doing.

Project Category: Relational Database Management System (RDBMS) : This is an RDBMS based project which is currently using MySQL for all the transaction statements. MySQL is an opensource RDBMS System. Brief Introduction about RDBSM : A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as invented by E. F. Codd, of IBM's San Jose Research Laboratory. Many popular databases currently in use are based on the relational database model. RDBMSs have become a predominant choice for the storage of information in new databases used for financial records, manufacturing and logistical information, personnel data, and much more since the 1980s. Relational databases have often replaced legacy hierarchical databases and network databases because they are easier to understand and use. However, relational databases have been challenged by object databases, which were introduced in an attempt to address the objectrelational impedance mismatch in relational database, and XML databases.

SYSTEM ANALYSIS The analysis model is a concise, precise abstraction of what the desired system must do, and not how it will be done after the study of the existing system is completed. This basically includes
system
study
and
the
requirement
analysis.
Interacting with the clients regarding their requirements and expectations from the system does requirement analysis. The steps, which are essential for system analysis, are: 1. Research and define essential components. 2. Analyze current processes and identify gaps. 3. Interview users, Trainee, Trainers and other concerned personnel
regarding
essential
components
and
current
processes. 4. Write requirements document. 5. Define standards for standards, policies, and procedures. 6. Review draft requirements document with users, Trainee, Trainers and other concerned personnel. 7. Update and expand project plan.

FEASIBILITY STUDY At this stage, the analyst estimates the urgency of the project and estimates the development cost. In feasibility analysis, we have to study the following: 1) Technical Feasibility: Technical feasibility is concerned with the availability of hardware and software required for the development of the system, to see compatibility and maturity of the technology proposed to be used and to see the availability of the required technical manpower to develop the system. After the study we came to conclusion that we proceed further with the tools and development environment chosen by us. This was important in our case as we were working on two various phases of the department that will need to be integrated in future to make an extended system. 2) Operational Feasibility: Operational feasibility is all about problems that may arise during operations. There are two aspects related with this issue:
- (14) -
Examination Management System – VB 6.0
What is the probability that the solution developed may not be put to use or may not work? What is the inclination of the management and end users towards the solution? Though, there is very least possibility of management being averse to the solution, there is a significant probability that the end users may not be interested in using the solution due to lack of training, insight etc. 3) Economic Feasibility: It is the measure of cost effectiveness of the project. The economic feasibility is nothing but judging whether the possible benefit of solving the problems is worthwhile of not. At the feasibility study level, it is impossible to estimate the cost
because
member’s
requirements
and
alternative
solutions have not been identified at this stage. However, when the specific requirements and solutions have been identified, the analyst weighs the cost and benefits of all solutions, this is called “cost benefit analysis.

System Design In this phase, a logical system is built which fulfils the given requirements. Design phase of software development deals with transforming the customer’s requirements into a logically working system. Normally, design is performed in the following in the following two steps: 1) Primary Design Phase: In this phase, the system is designed at block level. The blocks are created on the basis of analysis done in the problem identification phase. Different blocks are created for different functions emphasis is put on minimising the information flow between blocks. Thus, all activities which require more interaction are kept in one block. 2) Secondary Design Phase : In the secondary phase the detailed design of every block is performed. The general tasks involved in the design process are the following: I. Design various blocks for overall system processes. II. Design smaller, compact and workable modules in each block. III. Design various database structures.

desired
functionality. V. Design the form of inputs, and outputs of the system. VI. Perform documentation of the design. VII. System reviews.
User Interface Design User Interface Design is concerned with the dialogue between a user and the computer. It is concerned with everything from starting the system or logging into the system to the eventually presentation of desired inputs and outputs. The overall flow of screens and messages is called a dialogue. The
following
steps
are
various
guidelines
for
User
Interface Design: 1) The system user should always be aware of what to do next. 2) The screen should be formatted so that various types of information, instructions and messages always appear in the same general display area.
- (20) -
Examination Management System – VB 6.0
3) Message, instructions or information should be displayed long enough to allow the system user to read them. 4) Use display attributes sparingly. 5) Default values for fields and answers to be entered by the user should be specified. 6) A user should not be allowed to proceed without correcting an error. 7) The system user should never get an operating system message or fatal error.

TESTING Testing is the process in which the system is run on manually created input so that the system is correctly working as desired or not. During systems testing, the system is used experimentally to ensure that the software does not fail. In other words, we can say that it will run according to its specifications and in the way users expect. Special test data are input for processing, and the results examined. A limited number of users may be allowed to use the system so that analyst can see whether they try to use it in unforeseen ways. It is desirable to discover any surprises before the organization implements the system and depends on it. Testing of a system is generally done in two phases – One is Unit Testing which is done for each module independently on its completion and the other one is System Testing which is done at the end of a project.

VALIDATION CRITERIA The validation criteria in this project are as follows... In E-Commerce Portal System also, the user inputs are validated before storing them, and then further for displaying etc. The main validations that are done in E-Commerce Portal System are as follows – All the screens have a similar look and feel. They all have the almost same color combinations in its background. This provides a better user interface to the users. 1) The primary key values cannot be duplicated. 2) All the entries in any combo box have been sorted in alphabetical order. This helps a user while selecting a value from the combo box.
IMPORTANCE OF TESTING During systems testing, the system is used experimentally to ensure that the software does not fail. In other words, we can say that it will run according to its specifications and in the way users expect. Special test data are input for processing, and the results examined. The importance of system testing is that the system is expected to run according to member’s requirement before delivering it to the customer.

Implementation and Testing
Implementation Detailed Design of Implementation - This phase of the systems development life cycle refines hardware and software specifications, establishes programming plans, trains users and implements extensive testing procedures, to evaluate design and operating specifications and/or provide the basis for further modification. Technical Design - This activity builds upon specifications produced during new system design, adding detailed technical specifications and documentation. Test Specifications and Planning - This activity prepares detailed test specifications for individual modules and programs, job streams, subsystems, and for the system as a whole. Programming and Testing - This activity encompasses actual development, writing, and testing of program units or modules. User Training - This activity encompasses writing user procedure manuals, preparation of user training materials, conducting
- (25) -
Examination Management System – VB 6.0
training programs, and testing procedures. Acceptance Test - A final procedural review to demonstrate a system and secure user approval before a system becomes operational. Installation Phase - In this phase the new Computerized system is installed, the conversion to new procedures is fully implemented, and the potential of the new system is explored. System Installation: The process of starting the actual use of a system and training user personnel in its operation. Review Phase - This phase evaluates the successes and failures during a systems development project, and to measure the results of a new Computerized Transystem in terms of benefits and savings projected at the start of the project. Development Recap - A review of a project immediately after completion to find successes and potential problems in future work. Post-Implementation Review - A review, conducted after a new system has been in operation for some time, to evaluate actual system performance against original expectations and projections
- (26) -
Examination Management System – VB 6.0
for cost-benefit improvements. Also identifies maintenance projects to enhance or improve the system.
THE STEPS IN THE SOFTWARE TESTING The steps involved during Unit testing are as follows: a) Preparation of the test cases. b) Preparation of the possible test data with all the validation checks. c) Complete code review of the module. d) Actual testing done manually. e) Modifications done for the errors found during testing. f) Prepared the test result scripts. The unit testing done included the testing of the following items: 1) Functionality of the entire module/forms. 2) Validations for user input. 3) Checking of the Coding standards to be maintained during coding. 4) Testing the module with all the possible test data. 5) Testing of the functionality involving all type of calculations etc. 6) Commenting standard in the source files. After completing the Unit testing of all the modules, the whole
- (27) -
Examination Management System – VB 6.0
system is integrated with all its dependencies in that module. While System Integration, We integrated the modules one by one and tested the system at each step. This helped in reduction of errors at the time of the system testing. The steps involved during System testing are as follows: Integration of all the modules/forms in the system. Preparation of the test cases. Preparation of the possible test data with all the validation checks. Actual testing done manually. Recording of all the reproduced errors. Modifications done for the errors found during testing. Prepared the test result scripts after rectification of the errors.
The System Testing done included the testing of the following items: 1. Functionality of the entire system as a whole. 2. User Interface of the system. 3. Testing the dependent modules together with all the possible
- (28) -
Examination Management System – VB 6.0
test data scripts. 4. Verification and Validation testing. 5. Testing the reports with all its functionality. After the completion of system testing, the next following phase was the Acceptance Testing. Clients at their end did this and accepted the system with appreciation. Thus, we reached the final phase of the project delivery. There are other six tests, which fall under special category. They are described below: i.
Peak Load Test: It determines whether the system will handle the volume of activities that occur when the system is at the peak of its processing demand. For example, test the system by activating all terminals at the same time.
ii.
Storage Testing: It determines the capacity of the system to store transaction data on a disk or in other files.
iii.
Performance Time Testing: it determines the length of time system used by the system to process transaction data. This test is conducted prior to implementation to determine how long it takes to get a response to an inquiry, make a backup copy of a file, or send a transmission and get a response.
- (29) -
Examination Management System – VB 6.0
iv.
Recovery Testing: This testing determines the ability of user to recover data or re-start system after failure. For example, load backup copy of data and resume processing without data or integrity loss.
v.
Procedure
Testing:
It
determines
the
clarity
of
documentation on operation and uses of system by having users do exactly what manuals request. For example, powering down system at the end of week or responding to paper-out light on printer. vi.
Human Factors Testing: It determines how users will use the system when processing data or preparing reports.

COST ESTIMATION OF THE PROJECT Software cost comprises a small percentage of overall computerbased system cost. There are a number of factors, which are considered, that can affect the ultimate cost of the software such as - human, technical, Hardware and Software availability etc. The main point that was considered during the cost estimation of project was its sizing. In spite of complete software sizing, function point and approximate lines of code were also used to "size" each element of the Software and their costing. The cost estimation done by me for Project also depend upon the baseline metrics collected from past projects and these were used in conjunction with estimation variables to develop cost and effort projections. We have basically estimated this project mainly on two bases 1) Effort Estimation - This refers to the total man-hours required for the development of the project. It even includes the time required for doing documentation and user manual. 2) Hardware Required Estimation - This includes the cost of the PCs and the hardware cost required for development of this project.
