ER Diagram
Business Rules
The main business rules used for the development of the system are:
 The details of the students are to be stored in the system and they are to be identified by a
unique StudentID.
 The system should be able to enrol the students into the system and store their details in the
members table.
 The system should also store the details of the services in the system with services ID.
The system should also be able to store the details of the jobs which are used for the services
and are allocated to the volunteers who would be performing the tasks.

DATABASE DESIGN AND DEVELOPMENT
 The system should be able to store the details of the volunteers who would be available for
performing the tasks.
Normalization
The database which has been created is already normalized to thirds normal. For example, the
Student table has been considered in this discussion.
Student (StudentID (pk), StudentName, StudentAddress, StudentContact)
In the table StudentID is the primary key and no other duplicate value in the field would be
accepted by the system. Hence this is already in the first normal form. In addition to this, there is only
a single key in the table which is StudentID and no other attribute provides the uniqueness in the table
and hence the table in in a 2nd normal form. Also all the attributes in the table are dependent on the
StudentID and no other attribute and hence, there are no transitive dependency in the table and the
table is in Third normal form.
