Master Database Testing & Complex SQL Queries

Learn how to write verification queries, validate ACID properties, inspect foreign keys, perform data migration audits, and detect backend data corruption. Database testing helps QA testers verify the accuracy, consistency, integrity, and security of stored data. Testers use SQL queries to validate records, check database operations, and identify backend defects. As a result, they can ensure that applications meet business requirements and handle data correctly.During testing, QA professionals check duplicate records, identify missing values, and verify data storage, updates, retrieval, and deletion. Additionally, they perform several types of testing, including data integrity testing, data validation, CRUD testing, stored procedure testing, and performance testing.
