After passing the tests, check the changes into the source code control system. Once a change has been verified, run all the unit tests against the sandbox database, which verifies not only the modified code but also that the change did not break any other code. You can refine this approach by writing one or more database unit tests to verify a change. This approach allows a developer to work in isolation without introducing instability into a shared database environment. Changes can now be deployed to a local sandbox database and manually tested. The imported project might raise some warnings, but after you clean up the warnings and the project builds successfully, you can check it into your source code control system.Īfter the project and source code have been checked in, developers on your team can retrieve the project and source code and work with them on their local computers. Once the definition of your database has been moved from a live database to an offline/modeled environment, database developers can apply agile or iterative development practices that have made application development leaner and less expensive.Ī database developer can begin developing offline by creating a database project in Visual Studio and then importing the current development database into the project. The process of editing script files without being connected to a database is known as offline schema development. Storing these objects as scripts means you can manage the scripts through a source code control system and allows more than one database developer to edit the scripts simultaneously and then merge them as appropriate when checking in changes. In VSTS Database Edition, objects (such as tables, stored procedures, and views) that make up your schema are managed in a Visual Studio database project as CREATE scripts. This approach does not provide any way to track and merge changes to database objects, which makes moving changes from one environment to another a very manual process. Historically, database schema development has required writing code against a shared development server and then writing update scripts to migrate changes from one environment to another.
