Also submit a document explaining what test data you used to test your constraints. This would be data that you aren't including in your insert data for this assignment because you were using it to make sure the constraints were working (that is, as long as everything is working correctly, the database won't accept it).
1) Create a database based on the below model.

3) Create SQL scripts for the assigned reports.
