SQL Server Data Tools (SSDT) extends SQL Server development beyond SQL Server Management Studio (SSMS). It supports advanced T-SQL work through Visual Studio and the SQL Server Database Project template. section 7.0
Avoid treating database backups and handcrafted deployment scripts as a complete source-control and deployment strategy:
- Keep T-SQL code in a source-control repository to preserve version history, enable rollback, and support multiple developers. section 7.0 section 7.7
- Use Visual Studio Database Projects for built-in SQL schema comparison, then use SSDT Schema Compare to understand changes and affected functionality before deployment. section 7.7
- Treat SSDT as part of a modern development and deployment workflow rather than a replacement for understanding deployment impact. section 7.0 section 7.7
