Assignment - Entity-Relationship Modeling

Please submit the three parts of this assignment using this document.

Part 1: Complete the table.

Part 2: Write a detail document about the various business rules and define how the described scenario works with respect to entities and their relationships.

Part 3: Create an E-R Diagram.

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.

3. Identify the entity that the Primary Key belongs to (write the name of the entity in the last column).

The first three rows are filled in to provide an example of how the table should be completed.

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.
