The data-tier application (DAC) type defines the data-tier objects used by an application. It defines instance-level objects such as logins and database objects, such as tables and stored procedures. The type contains a server selection policy that specifies the requirements an instance of the SQL Server Database Engine should meet in order to host the DAC. The type also contains miscellaneous files, such as pre- and post-deployment scripts.

A DAC type is developed in two ways. It is typically authored by using a DAC project in Microsoft Visual Studio. It can also be extracted from an existing database. The DAC type is built into a DAC package, which is an XML manifest of all the elements in the type. The DAC package is used to deploy the DAC type to an instance of the Database Engine. Each deployment creates a DAC instance, which contains both the DAC type from the package, and a database created to hold the objects defined in the DAC type.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
