For this exercise, list three entities (you cannot use the ones from the lesson) and five properties for each entity. State which property you think would serve well as a unique identifier, or if you would need to create an artificial property for that purpose.
The 3 entities I chose for this discussion are Employee, Inventory, and Patient with the following properties:
1. Employee
ID (Pk)
First Name
Last Name
Title
Business Unit
2. Inventory
Item # (Pk)
Description
Vendor
Price
Category
3. Patient
ID (Pk)
First Name
Last Name
Birthdate
Diagnosis.
