In the early 1990's several case tools had 'normalization support'. The feature was'nt worth the effort to the users. No demand for it.

I don't remember if it was IEF (Inormation Engineering Facility) or IEW (Information Engineering Workbench) which had quite exentensive support, but I do remember this support just did not help the design process at all. Received on Tue May 03 2005 - 00:17:39 CEST
