VINCE'S VINYL It is time to test Vince's database to see if it truly meets his needs. It is time to look back at the business rules and test them with some SQL. Look at the business rules you devel- oped previously, and design some SQL queries to test them. Documentation: Set up a test plan. List the rule, the SQL you wrote, and the results. Also note whether the database passes or fails the test. Your queries should include the following: • Two or three simple SELECTS with various WHERE criteria. • Two or three queries using aggregate functions. At least two queries that use joins. ● Two or three INSERT statements. One or two UPDATES and/or a DELETE. VINCE'S VINYL It is time to test Vince's database to see if it truly meets his needs.
