Review the Personal Trainer fact-finding summary in Chapter 4 and draw an ERD with cardinality notation.


1. Review the Personal Trainer fact-finding summary in Chapter 4 and draw an ERD with cardinality notation. Assume that system entities include members, activities and services, and fitness instructors.
2. Design tables in 3NF. As you create the database, include various codes for at least three of the fields.
3. Use sample data to populate the fields for at least three records in each table.
4. Recommend a date format for the new system. Should Personal Trainer adopt a single international standard, or should the format be determined by the country in which the center is located? Write a message to Susan with your recommendations.
