IntroductionOffline examiner is a real time project. The project will be implemented using VB. The aim of the project is to allow teachers to conduct examinations to the students. There are many unique features in the project. The students are not allowed to go back to the previous question once they click the next question. This option is up to the teachers to decide the teachers can either enable such an option or disable the option. The teachers are also given option to set the time limit of the exam.Various types of reports can be generated both for the teachers as well as the Administrators.The software will be used by three different types of users namely:-StudentsStaffsAdministrators

 Nature and Scope of “On-Line Examination”:Teachers can add new questions to the exam paper

Teachers can set the duration of the exam

Students attend the exam

Administrators can generate various types of reports

 Administrators can enable security settings

Print out of the grade sheet is issued when the student completes the exam, or when the duration is finishedStudents can view their past exam history.

Existing System:-Lack of security of data.More man power.Time consuming.Consumes large volume of pare work.Needs manual calculations.PROPOSED SYSTEM:-Security of data.Proper control of the higher officials.Minimize manual data entry.Greater efficiency.Better service.Minimum time required.

Need of System:-

HARDWARE REQUIREMENTS

Processor : X86 Compatible processor with 1.7 GHz Clock speed RAM : 512 MB or more Hard disk : 20 GB or more Monitor : VGA/SVGA Keyboard : 104 Keys Mouse : 2 buttons/ 3 buttons 

System Requirement

Software Requirement:-

Operating System : Windows 2000/XP Front end : Visual Basic 6.0 Back end : oracle 10g 

Testing PlanningTesting Planning

Project Organization:- The s/w testing consists of levels of testing:1)Unit testing2)Integration testing3)System testing

1)UNIT TESTING: This testing forces verification efforts on the smallest of the s/w. While doing this, each module was tested to see that information properly flows into and out of the program under consideration.

2)INTEGRATION TESTING: Once all modules have been tested individually, then system is tested by integrating modules.

3)SYSTEM TESTING: Last of all the whole system is tested to find weather the system and its original objectives tally.

Technical OverviewTechnical Overview

Language Used:-Language used Visual Basic:- Visual basic 6.0 for windows requires at least windows-95 and minimum of 16MB of RAM. A complete installation of visual basic 6.0 requires more than 250MB of hard disk space.DATABASE: ORACLETo store the records of the students or database we require oracle as a backend. In addition to this it also act as a front-end. Using oracle forms can be created that act as a interface between user and the tables.
