DBU is the original database utility on the iSeries AS/400, which allows users to view and update any file instantly without using time-consuming queries, DFU or programming. The newest release offers a GUI with ?explorer? like features for the AS/400 file systems. It is also accessible thru iSeries Navigator and WDSc. With DBU 6.0, you can let some of your staff continue with the traditional green screen or allow them to venture into GUI for quick database access.
