INTRODUCTION
Schools of KVS are one of the renouned Institutions of
India , students and as well as teacher of it are indulged not only
in academic but also many co-curicular activities. Since it is a
Govt. of India undertaken Institution there fore it has a lot of
paper works to be done , usually they are done by maintaining
huge registers, from the entry of a person in vidyalaya to the lists
of TC issued students, all are manually recorded. It increases a lot
of data redundancy and personal errors done by the staffs.So by
maintaining a digital record the effort is reduced a lot and
secondly a large amount of energy and resourses is saved.
Since a school has a lot of elements that is to be
recorded manually therefore combining all of them in one
programe will be a very tough job. So I have designed my program
in C++ to cover some of its aspects. My programe is associated
with basic database of all teachers and student containing the bio
data of them , it allows to add , delete ,edit biodata of
students.And it also contains a ID no based entry system that’s
records the entry of a particular person.

Testing
This program is made by me after lots of troubles
and errors. Firstly, I checked the program and finds
some errors and then myself corrected them . After
that I asked my computer science sir to verify it but
he finds small errors in my program and asked me to
correct them. Then with the given suggestion of my
sir I corrected them.
Lastly, I asked my computer science sir to give a last
look in it and with his blessings I completed my
project.
CONCLUSION OF PROJECTCONCLUSION OF PROJECTCONCLUSION OF PROJECTCONCLUSION OF PROJECT
My project is on School database management and Id based entry system.
I have successfully completed it. I take this opportunity to express my
sense of indebtedness and gratitude to all those people who helped us in
completing this project.
I am immensely grateful to Mr. Sanwar Mal(PGT comp. sc) for his
supervision and guidance without which this work would not have been
possible....This project has contributed a lot to my knowledge that has
proved to be a value addition for me.
