ERD: Physical Entity Relationship Diagram
• Choose one of the below scenarios and Create the physical level ERD. (You may choose the same or different
scenario to the one you worked on in Exercise 1). You must create the ERD using Microsoft Visio or other
diagram drawing software as indicated by your professor. Make sure to submit a PDF version of your diagram
along with the actual diagram file (in case your professor can’t open your Visio file, they can use the PDF file
to grade). Make sure to submit the diagram by the due date as specified by your professor.
Scenario 1:
This is a simple list table of a company trying to keep track of parts that they sell and orders that came in purchasing
those parts (in other words, not a database but a flat one table file). You will design a database for this company so that
they won’t be relying on a simple 1 table list system to keep track of their data. Looking at the table below, identify the
separate entities and attributes and design a physical level Entity Relationship Diagram for this company.
