Step 1: Identify the entities and relationships.

a. Over the past four weeks, you have created ERDs based on information provided. This week, you will complete the ERD being sure to normalize it to 3NF (third normal form). Normalization is the systematic application of rules designed to eliminate redundancy from the database. Data in previous weeks was, to some extent, normalized for you. This week, it is not. An abbreviated list of the data requirements follows.
