The document discusses various types of database testing including data integrity testing, stored procedure testing, data type testing, data size testing, event driven testing, and input item verification. Data integrity testing ensures that changes to data, like updates, deletions, and insertions, properly update related entities. Stored procedure testing involves testing individual functions and validating modularity. Data type testing checks that data types match between developers and database administrators. Data size testing verifies performance with large amounts of data bypassing front-end validation. Event driven testing checks triggers and scheduled actions. And input item verification tests for proper data validation of user inputs.
