Students form a main part of any institution that concerns with. But the institutions find it difficult to keep details of so many students of the organization just in one stretch. It will involve a lot of pen paper work. Sometimes there will be some huge heap of files bundled up and kept together in some corner of the office. It will be the files that will contain the details of the students of the institution. To solve all these problems, the student information system applications can a play a major role. The student information system ER (Entity Relationship diagram) will play a major role in illustrating the logical structure of the databases.

The entity is a concept or object in which the piece of information can be stored. There are three types of relationship between entities. They are as follows:

• One to One(1-1): This relationship specifies that one instance of an entity is associated with another instance of an entity.
• One to Many(1-N): This relationship specifies that one instance of an entity is associated with zero or many other instances of another entity.
• Many to Many(N-N): This relationship specifies that one instance of an entity is associated with zero or many other instances of another entity.

The student information system application will help in managing the student’s reports, results and exams will become easier with one such system. It will also help in saving time and effort. The user interface must be user friendly and easy to understand. The authorized users will be having access to the system through the use of login id and the password. The performance of the students might be in curriculum as well as co-curriculum can also be stored through the use of this application. The data that will be disclosed will be more secure since there will be no access to the unknown users.
