You can import data from the data sources in the following table. When you install [!INCLUDE[ssBIDevStudioFull](../../includes/ssbidevstudiofull-md.md)], setup does not install the providers that are listed for each data source. Some providers might already be installed with other applications on your computer; in other cases you will need to download and install the provider.

## <aname="bkmk_supported_ds_dq"></a> Supported data sources for DirectQuery models

-
DirectQuery is an alternative to in-memory storage mode, routing queries to and returning results directly from backend data systems rather than storing all data inside the model (and in RAM once the model is loaded). Because Analysis Services has to formulate queries in the native database query syntax, a smaller subset of data sources are supported for this mode.

Columns that contain similar data in different data sources are the basis of creating relationships within the model designer. When using heterogeneous data sources, choose tables that have columns that can be mapped to tables in other data sources that contain identical or similar data.
