Microsoft SQL Server is a database platform with a T-SQL engine, administration tooling and editions for different workloads. It runs on supported Windows and Linux environments as well as cloud infrastructure. Express offers a limited free production route, while Developer editions are for non-production work. Choosing a deployment means checking the edition, operating environment and production licensing together.
