8. FUTURE SCOPE OF THE PROJECT This system is developed to full fill the need of any institute who wants to be online and global. The main feature of this system is to provide quick result and information to satisfy the students.
In future, the modification can be made according to the requirement of the institute. The greatest amount of maintenance work is for user enhancement and improved documentation of this system for better efficiency. We can update the documentation, test data and upgrade user support.

8. FUTURE SCOPE OF THE PROJECT This system is developed to full fill the need of any institute who wants to be online and global. The main feature of this system is to provide quick result and information to satisfy the students.
In future, the modification can be made according to the requirement of the institute. The greatest amount of maintenance work is for user enhancement and improved documentation of this system for better efficiency. We can update the documentation, test data and upgrade user support.
