BPCS is a commercial product – need to be at a site where they have the manuals
Synon, Now CA 2e, is a code generator, for which manuals can be downloaded from the www.ca.com site. One of them is the legendary ‘Horse race Model’ example training manual.
You can also get plenty of support at the forum, and on the Wiki.
Again – having a box and a mentor is key to the process. 2e is *all* about the database design. The product os old enough for there to be lots of either bad or just outdated code out there.
