The process of checking data integrity and consistency of the database is called database testing. Ultimately, it aims to create complex queries to check database responsiveness to load/stress putting schema, tables, triggers, stored procedures, etc., under test. DB testing tools need to cover all tiers of database testing, including the business, data access, UI, and the database itself. These tools have to be reliable, user-friendly and provide great performance. The need for a stronger and secure database increases in direct proportion to the complexity of the application.
