Submit the table creation statements (including constraints) for the Database Model. Submit them all in a single script file.
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.
Save your table creation statements as a script (you'll be submitting this script). Your script should follow the diagram exactly. Be sure to include the necessary constraints.
2) Create sample data. (See below for some sample data) Save the scripts that load the data. Test the constraints with appropriate data. The data will be used for the reports described next.
3) Create SQL scripts for the assigned reports.
