What is database testing and how to do it?
It involves creating complex queries for performing the load or stress test on the database and check its responsiveness. It checks integrity and consistency of data. Database testing usually consists of a layered process that includes the User Interface (UI) layer, the business layer, the data access layer and the database.

Therefore, there is a need to check database components regularly. In addition, data integrity and consistency should be checked regularly. Database testing is different from front-end UI testing. The following table highlights the key differences − Database testing is known as data validation and integrity testing or back-end testing.
Why database testing is performed on backend system?
Testing at the backend system increases the robustness of the data. That is why database testing is performed on back end system. In a database, data comes from multiple applications and there is a possibility that harmful or incorrect data is stored in the database. Therefore, there is a need to check database components regularly.
Why do database tests take so long to execute?
Depending on their design and data size, some database tests may take a long time to execute. As the database size is too large, it becomes a big challenge to find out the objects that have to be tested and those which are to be left out. Normally testers are provided with a copy of the development database to test.
