Having submitted your project domain proposal (and received
approval), your first step is to construct an entity-relationship
diagram for the data. As suggested in Project 0 assignment,
your entity-relationship diagram should reflect a moderate number of
entity sets and relationships -- in the 8-14 range.
You should certainly include different kinds of relationships (e.g., many-one, many-many) and different kinds of data (strings, integers, etc.), but your application is not required to use advanced features, such as subclassing, multiway relationsships, or weak entity sets, if they are not appropriate for your application.
Also, don't forget to save a copy of your E/R diagram for
reference as you do Part 2 of the PDA.
