Microsoft’s investments in application and multi-server management will help reduce the complexity around developing, deploying, and managing applications. A core concept of application and multi-server management in SQL Server is the data-tier application (DAC). A DAC, introduced in the Microsoft® SQL Server® 2008 R2 data management software and the Microsoft Visual Studio® 2010 development system, is a self-contained unit of deployment that defines and bundles database objects, SQL Server instance objects that are associated with the database, and deployment requirements of an application. Using DACs, developers and database administrators can automate and facilitate common operations and practices in the lifecycle of database systems.
