# BackendType

The type of back end you want to use for the fact store component. This parameter is used only for systems that have Type set to `Factbank`.

You can use one of the following values:

- sqldb. Use an SQL database. In this case, you must also set ConnectionString to the connection string to use to connect to the fact store database.

- lua. Use a custom Lua script. In this case, you must also set ScriptPath to specify the Lua script that you want to use, and you can optionally set ScriptFunction to the name of the entry function that Answer Server must call.

- Content. Use an IDOL Content component. In this case, you must also set IDOLHost and IDOLACIPort to the host name and port of the IDOL Content component to use.

  DEPRECATED: The IDOL Content component fact store is deprecated from Answer Server version 11.5. Micro Focus recommends that you use a SQL database instead.

  The `Content` option is still available for existing implementations, but it might be incompatible with new functionality. The option might be deleted in future.

For all backends, you must configure the question parser Eduction grammars by using the EductionQuestionGrammars and EductionTimeGrammars parameters, and configure the coding files by using the CodingsDatPath and CodingsPath parameters.
