As I said in a previous post, our business objects don't reference each other via there OID, so no it's not important for me. And yes the OPF frameworks takes care of the nitty gritty stuff. For those not using the tools I use, might not be so luck. In example... Using the standard DB components in Delphi or Lazarus and using Master/Details grids and tables, you need to save the master record first, find out the unique identifier of the master record, include that in the SQL for the detail records. In the this example you need a extra round trip to the database if your application can't generate a unique identifier itself. GUID's make this a no brainer. :) Regards, - Graeme - _______________________________________________________ fpGUI - a cross-platform GUI toolkit using Free Pascal http://opensoft.homeip.net/fpgui/ _______________________________________________ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
