So what type of > data flows do you envision Loci supporting. One-to-one, one-to-many, > many-to-one? I guess I misread this the first time. I wouldn't say my thinking is NOT data centric.

But maybe my view is a little more flow oriented. :-) Jeff -- J.W. Bizzaro mailto:bizzaro at bc.edu Boston College Chemistry http://www.uml.edu/Dept/Chem/Bizzaro/ --
