I don’t understand this Health & Medical question and need help to study.
the requirement of this assignment is :
Find an example Entity Relationship Diagram on the Internet. Google Images search is great for doing this. Post or link to an example that other students have not posted.
Explain the what type of business the database is for and if you can determine how the business works based on how the diagram is constructed (e.g. orders can have a priority status). Pick one relationship and state how the two entities are related (e.g. A customer can place many orders; An order can be placed by one and only customer).
Critique the diagram and either point out its strengths or how it can be improved or if the original author made an errors.
also I have attached a student example to have an idea before you do it
