Basic SQL for Software Testers

Designed for applied learning, Basic SQL for Software Testers shows how to use SQL to inspect application data, verify business rules and investigate mismatches between interfaces, APIs and stored records. It combines relational data for testers with safe query practice, then extends the work through select essentials. Learners query a safe sample database, filter and join tables, handle nulls and aggregates, compare expected transactions with persisted data and document checks without altering protected information. Participants examine both successful and weak examples, build reusable working habits and consider where human review is essential. The course builds database confidence for functional, API and integration testing while reinforcing read-only practice, data privacy and reproducible evidence.
