Need help in ER diagram
Create a diagram for a database with at least 5 tables. This should show your table names and column names. Show the relationships between
the tables. Write a statement explaining your database design (why did you use the tables that you did).
Create a database in Access based on your diagram. Include all tables in your diagram. Tables should each have a minimum of 5 rows.
