Part 1: Complete the Table

Fill out the table by following these instructions:

1. For each piece of information that the school wants to track, identify if it is an entity or an attribute (place an X in the appropriate column).

2. For each recognized attribute, identify if it is a primary key with an X in the Primary Key column.

Part 2: Write a Detail Document

Using the provided information, write a detail document about the various scenarios described in Part 1 with respect to entities and their relationships. The E-R Diagram will be created from your findings. Don't worry about going through the normalization process at this point. Identify the appropriate relationships among the entities and define the minimum and maximum cardinality of each relationship. Make some additional assumptions about the business rules if necessary.

Part 3: Create an E-R Diagram

Draw the initial E-R diagram based on the given business rules and the scenarios you defined in your detail document. Include a screen shot or jpeg of the E-R diagram in the CT03_assignment document for submission.
