* If, however, the accessing the data invovles more work (e.g. parsing

* information you will need later. Then use the saved information in
* usmDHUserKeyTable_row_prep() for populating data.
*
* @note
* If you need consistency between rows (like you want statistics
* for each row to be from the same time frame), you should set all
