WDSC vs Rational
A common question that's asked is: What is the difference between WDSC and RAD?
Joe Pluta provide a very concise answer...
As of version 7, the issue is this:
Eclipse + Rational J2EE stuff = RWD RWD + System i extensions = WDSC
RWD + EJB = RAD RAD + System i extensions = WDSC Advanced Edition
This is grossly over-simplified, but that's the gist of it. The primary difference between Rational and WDSC is the System i extensions, which is pretty much made up of the views you listed in your original post. And the primary difference between the basic and advanced (RWD vs RAD, or WDSC vs WDSC AE) is EJB support.
However, this changes soon. Most likely in the next release, there will be no RWD/RAD, there will only be RAD. Similarly, there will be no more WDSC AE, there will only be WDSC (and it will probably be called RDi).
