The ADOMD.NET data provider is used to access multidimensional data sources, such as Microsoft SQL Server 2005 Analysis Services (SSAS), in managed code. Using the AdomdConnection, you can connect to a multidimensional data source, and you can then run queries and statements using an AdomdCommand to return AdomdDataReader and CellSet objects containing multidimensional data. You can also use the AdomdConnection to view metadata for multidimensional data sources, either by examining the CubeDef and related objects or by retrieving schema rowsets directly from the data source.

For more information, see ADOMD.NET Client Programming.
