Computer Associates International Inc has added a three-dimensional navigation module called TNG, The Next Generation, to its CA-Unicenter systems management environment, use of which it likens to the way video games players can fly over landscapes and zoom in on cities and buildings. As users navigate down through individual computers to database processes and user indentifications, the new TNG alerts managers to events requiring attention with a blinking light. Clicking on an object brings up information about that object and tools associated with it.
