Database Testing is a process that ensures the integrity, reliability, and performance of a database. It involves verifying that the data stored in the database is accurate, consistent, and accessible. Testers check for issues such as data corruption, incorrect data types, and proper indexing to ensure that the database functions as intended. During Database Testing, various techniques are employed, including data validation, data integrity checks, and performance testing. These methods help identify potential problems before the database is deployed in a live environment, ensuring that applications relying on the database can operate smoothly and efficiently.
