Source control systems have been successfully used for years by developers for collaborating without colliding. Todays DBA's must work closely with development teams to ensure that the solutions created are optimal. We will review the outlines of various source control platforms including Microsoft Team Foundation Server, Subversion and Mercurial and how to interact with them. The second half of the session will be an overview and discussion of techniques and practices to provide database versioning and how to ensure that every build of the application is able to have a matching version of the database.
