Power BI data sources
Power BI uses Power Query to connect to data sources. Power BI data sources are documented in the following article: Power Query (including Power BI) connectors.
For information about dataflows in Power BI, see connect to data sources for Power BI dataflows.
Considerations and limitations
- Many data connectors for Power BI Desktop require Internet Explorer 10 (or newer) for authentication.
- Some data sources are available in Power BI Desktop optimized for Power BI Report Server, but aren't supported when published to Power BI Report Server. See Power BI report data sources in Power BI Report Server for the list of supported data sources.
- Power BI Desktop and the Power BI service may send multiple queries for any given query, to get schema information or the data itself, based in part on whether data is cached. This behavior is by design, for more information see the Power Query article that describes why a query may run multiple times.
