Some business rules given in the case study
may not be clear to you when you read the case study. You may simply make an
assumption and then develop your ER model.
You are required to write brief definitions for the entities and attributes in your
model. For each entity and attribute in
your model, write a sentence to describe the meaning of that entity or
attribute.
What you need to should submit
You should submit a Microsoft Word document containing:
·
A copy of your entity-relationship
model.
·
A list of business rules that
are apparent from the case study.
·
A list of any assumptions that
you made with justifications.
Part-II Relational database implementation
You
must implement the entity relationship model based on Assignment 1.
The
recommended tool for this assignment is Microsoft Access.
In
implementing the ERD provided, you must complete the following tasks:
Map the ERD into a set of relations in at least Third
Normal Form (3NF). You must ensure that your relations meet 3NF.
Show your working.
List all the functional dependencies present in the
relation
Create all the relations in a Microsoft Access database. Consider each attribute in every table and
make appropriate choices regarding data
types and sizes, indexes, required/not required, and validation rules. Your choices should be appropriate for each
attribute and should support data integrity.
