Why use Visual Studio SSDT?

1) Speeds development.

2) Reduces coding errors.

Visual Studio with SQL Server Data Tools (SSDT) transforms the SQL Server Database development process from single-object creation and editing to solution-based database development, maintenance, and deployment.

Solutions based paradigm brings the same features and tools available with object oriented languages: version control, build verification, unit testing, CI/CD, IntelliSense, code navigation, refactoring, and custom object templates.

Developers work with a database projects or connected databases – whether the database is local, on-premise, or in the cloud.
