INTRODUCTION
In the current scenario, evaluating internal grade of students in the campus is time consuming as well as requires more human effort. Proposed system is an application program that provides a comprehensive solution to manage and enhance the internal mark evaluation.
Our project “INTERNAL MARK ASSESSMENT SYSTEM” is developed based on information collected from the various departments of ‘ Nirmala College, Muvattupuzha’.
This project mainly includes the maintains of admission details and internal details of each student in the department. Internal grade are evaluated from the grade obtained by the students for internal exams, seminars, assignment and attendance.
It is data base project. The proposed system is developed in visual Basic 6.0. SQL Server is the back end.
ABOUT THE ORGANIZATION
The project entitled “INTERNAL MARK ASSESSMENT SYSTEM “ computerize the internal grade calculation of various departments in Nirmala College.
Nirmala College is a first grade college, which entered into 59th year of its glorious service to the cause of higher education . In 1955,the college was raised to First Grade by B.A.,B.Sc and B.Com Courses. Post Graduate courses were introduced in 1965 and now there are 13 graduate courses and 8 Post Graduate courses are available and research facilities are available in 5 courses.
Nirmala College is one of the foremost colleges in Kerala with over 1500 faculty members. The college is affiliated to Mahatma Gandhi University , Kottayam.
Features of SQL Server 2000
Enterprise-Level Database Features:
The SQL Server 2000 relational database engine supports the features required to support demanding data processing environments. The database engine protects data integrity while minimizing the over head of managing thousands of users concurrently modifying the database.SQL Server 2000 distributed queries have been plugged into the .net allow you to reference data from multiple sources as if it were a part of a SQL Server 2000 database while at the same time, the distributed transaction support protects the integrity of any updates of the distribute data. Replication allows you to also maintain multiple copies of data, while ensuring that the separate copies remain synchronized. You can replicate a set of data to multiple, mobile, disconnected users, have them work autonomously, and then merge their modifications back to the publisher.
DATAFLOW DIAGRAMS(DFD)
The data flow diagrams were first developed by Larry Constantine as a way of expressing system requirements in a graphical form :this led to a modular design. A DFD, also known as “Bubble Chart” , has the purpose of clarifying system requirements and identifying major transformation that will become programs in system design. A DFD consists of a sequence of bubbles joined by lines . The bubbles represent data transformation and the line represent the data flow in system.
SYSTEM TESTING
The testing phase is an important part of software development. It is the processes of finding errors and missing operations and also a complete verifications to determine whether the objectives are requirements are satisfied. Software testing is carried out in three steps .
The first step includes unit testing where in each module is tested to provide its correctness, to determine any missing operations and to verify whether the objectives have been met. Errors are noted down and corrected immediately. Unit testing is the important and major part of the project. So errors are rectified easily in particular modules and program quality is increased. In this project, entire system is divided into several modules .
Second step include integration testing .If we need not be the case that software whose modules when run individually and showing perfect result with also show perfect result as whole .The individual modules are clipped under this major module and tested again and verified the results. A module can have inadvertent, adverse effect on any other on the global data structure causing serious problems.
The final step involves validation and testing which determines whether the software function as the user expected.
Artificial Data:
Artificial data are usually created for running the first test. The data should contain all possible combinations formats and values . Artificial data should include deliberate mistakes, such as numbers occurring on an alphabet-input field where a program expects a name. The mistake takes us to check the system editing , errors and corrections procedures.
