         This is especially useful when passing the entire result of MDX directly to a stored procedure in a database. 
         It allows you to map MDX column names to input parameter names of the stored procedure.

+
+        Rather than just returning the MDX results to the HTTP client, the optional argument ``pass_result_to_url`` can be used to 
+        forward these result data directly to a database stored procedure for storage or further processing. The stored procedure is exposed as a URL 
+        through `DbWebApi <https://github.com/DataBooster/DbWebApi>`_, such as ``http://dbwebapi.dev.com/oradev/the_schema.etl_package.load_mdx_result`` 
+        *(example for Oracle)* or ``http://dbwebapi.dev.com/sqldev/the_db.dbo.load_mdx_result`` *(example for SQL Server)*.

+        ``more_args``
+
+        Other than above MDX result data, your stored procedure may require more input parameters. 
+        The ``more_args`` argument (a dictionary) allows you to prepare all other input parameters required by the stored procedure into the dictionary.

+        ``notify_url``
+
+        Sometimes we may need to send a notification to somewhere when above process get completed or an error is encountered. 
+        The ``notify_url`` argument allows you to specify the URL of the notification destination *(it must also be a RESTful service)*.
+
+        ``notify_args``
+
+        This is also a dictionary, any items it carries will be passed to the notification service as input arguments.
