BIRT Analytics Loader loads data into a FastDB database repository, operated by the FastDB Engine. When FastDB is installed, a default data repository is created in this path:

You can use the same repository to create and store your databases. BIRT Analytics allows you to create a different location for your database repository and set up BIRT Loader to work with this location. For more information on how to create and set up a new data repository, see Administering BIRT Loader.
