Purpose of the Database The purpose of the database is to allow the

developers and users to pull out particular sets of information through queries within our application…. To retrieve data.

(Essentially this version is a draft version due to the fact secure shell is not the software we will be using to implement our app.)

The Makeup of Our Database Modeled after our ER diagram

Database contains 16 different tables each with its own set of attributes depending on what they are.

Sixteen Tables Stud admin E_coordinator Safety official Parking services Classes Class section Class roll
