Connected model statements enable you to interact with a data source. The FILL commands retrieve data from a data source and
               place it into the DataTables of a DataSet. The UPDATE commands ensure that any Data Manipulation Language (DML) changes (INSERT,
               UPDATE, and DELETE) are returned to the data source.
            
            
            The following connected model statements are available to you:
            
            
               
               -  PREPARE TO FILL – signals the DataSet to be filled
-  TO FILL USE – specifies the logic to retrieve data from table in data source to DataTable in DataSet
-  FILL – does the actual fill of the DataTables
-  PREPARE TO UPDATE – signals the DataSet whose DML changes are to be placed in a data source
-  TO DELETE USE – specifies the delete logic to be used in a data source
-  TO INSERT USE – specifies the insert logic to be used in a data source
-  TO REFRESH USE – specifies the refresh logic to be used in a data source
-  TO UPDATE USE – specified the update logic to be used in a data source
-  UPDATE – does the actual update to a data source
