An entity relationship diagram provides a roadmap for database design. It is essential to ensuring that entities include the correct information, including relationships. Think of a transaction that you complete, such as a purchase, signing up for a membership or anything that requires you to enter information. Create an ERD showing the entities, attributes, and relationships. Your ERD should identify the primary and foreign keys. You should provide the ERD diagram inserted into your DQ$,$ if not, attach it in an easy to read format to your post $($PDF is best$).$ Describe the relationships between the tables $($cardinality$)$ and why they exist. Do not use the examples from the critical thinking assignment.
