1. Imagine you are going to help Fuzzy Logic Raido with their data modeling.

2. Outline to others (that will read your post) what you might expect some of the Entities, Attributes, Relationships, and Constraints might be. Besides listing Entities and Attributes, express the relationships and constraints as business rules. Don't forget that relationships go two ways, e.g. A Customer generates many invoices. An invoice is generated by one customer, etc.

Thank you to anyone viewing it.
