STUDENT INFORMATION SYSTEM The Student information System is a software project that runs on Swing Environment in java. This application helps to store the student’s basic information in the database. Apart from storing, it maintains the information by doing proper updation in the database.

FUTURE ENHANCEMENTS

47

 Student information system can be implemented to get records class wise or section wise or gender wise etc.  During student’s admission process all the student’s details can be easily entered in the database.  The attendance of the students can be maintained.  The time table for each and every class can be maintained.  The performance of every student can be monitored and reports can be given to parents. CODING STANDARDS

 Use proper names methods.  All variables must begin with a small alphabet and follow

Hungarian

Notation.

E.g.

driverName,

vehicleName  Constants must be declared in capital letters.  Unnecessary import from java.lang.  Empty finally blocks.  Empty catch block.  Avoid

using variables with no proper descriptions.

48

 For loops use variables such as counter instead of using “x” or “i”. REFERENCES: 1)
