Introduction
This is a group assignment (at most 4 people in each group). It is the responsibility
of the group to allocate responsibilities among members clearly such that individual
contributions can be easily accessed. You are to submit the product of your work in
the form of a neatly formatted, type-written report (pdf format). The introductory part
of the report should state clearly how responsibilities were allocated and what
contributions each group member made. You should also make sure that you clearly
acknowledge sources you used to do your research, that is, quote and provide
references where applicable.

c) Data Integrity –How are appropriate business rules specified?

2. Advantages as compared to the relational data model.
