Description
Introduction
For this assignment, you will be converting the following ER diagram, which models the operational data for
a department store, to a set of relations that conform to Third Normal Form (3NF). Use the steps from the
slides that we went over in class. Make sure to indicate the primary keys by underlining them. Include a list
of which attributes are foreign keys, with the home relation of each foreign key indicated.

Figure 1: This is the ER diagram. There may be some things that may seem weird. These may be errors
that were missed during the design phase, or they could be intentional. The purpose of this assignment is to
convert it, not to revise it.
