The class represents the set of data-tier objects, policies, and properties developed and deployed to support a specific application.
Assembly: Microsoft.SqlServer.Management.Dac (in Microsoft.SqlServer.Management.Dac.dll)
Thetype exposes the following members.
|DacType()||Intializes a default object.|
|DacType(IServer, String, Version, String, Policy, MiscellaneousFilesCollection)||Initializes a new instance of the class with the specified definition, name, version, description, server selection policy, and set of miscellaneous files.|
|Definition||Gets an IServer object that represents a graph of the elements in the DAC type.|
|Description||Gets a String that describes the DAC type.|
|MiscellaneousFiles||Gets an enumerator that iterates through the miscellaneous files associated with the DAC type.|
|Name||Gets the application name of the DAC type.|
|TargetSelectionPolicy||Gets the server selection policy that defines the requirements an instance of the Database Engine should meet in order to host the DAC type.|
|Version||Gets the version of the DAC type.|
|Equals||(Inherited from Object.)|
|Finalize||(Inherited from Object.)|
|GetHashCode||(Inherited from Object.)|
|GetSchemaContentSize||Gets the content size of the DAC package that is referenced by the specified stream.|
|GetType||(Inherited from Object.)|
|Load(Stream)||Deserializes the input from a object pointing to a saved DAC type into a object.|
|Load(Stream, Boolean)||Deserializes the input from a object pointing to a saved DAC type into a object, with the option for loading elements other than the DAC type metadata.|
|MemberwiseClone||(Inherited from Object.)|
|Save||Serializes the contents of a object into an XML stream that is sent to the specified object.|
|ToString||(Inherited from Object.)|
|Unpack||Unpacks a DAC type into the specified folder.|
|ValidateDescription||Verifies that the description of the DAC type does not exceed the maximum length.|
|ValidateName||Verifies that the application name of the DAC type is not null and does not exceed the maximum length.|
|ValidateTargetSelectionPolicy||Verifies that the server selection policy for the DAC type is valid.|
|IXmlSerializable.ReadXml||Deserializes the DAC type properties from an XML stream. Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.|
|IXmlSerializable.WriteXml||Serializes the DAC type properties to an XML stream. Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.|
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.
