TC-001	Verify data integrity	1. Retrieve a record from the database. 2. Modify a value in the record. 3. Update the record in the database. 4. Retrieve the updated record from the database.	The modified value should be reflected in the updated record.
TC-002	Verify data validation	1. Attempt to insert a record with invalid data into the database. 2. Attempt to update a record with invalid data in the database.	The database should reject the invalid data and return an error message.
TC-003	Verify data security	1. Attempt to access the database without proper authentication. 2. Attempt to access a record in the database that the user does not have permission to access.	The database should deny access and return an error message.
TC-004	Verify performance	1. Insert a large number of records into the database. 2. Retrieve a large number of records from the database. 3. Update a large number of records in the database. 4. Delete a large number of records from the database.	The database should be able to handle the operations within an acceptable timeframe without slowing down or crashing.

Scenario:

You are a database administrator for a company that sells products online. You have a database that contains information about products, customers, orders, and shipments. Your goal is to ensure that the database is reliable, efficient, and secure.
