I took a nosedive into Data Integrator a couple of weeks ago.
The first thing I discovered was : they went to a lot of trouble trying to make an interface as un-intuitive as possible. The first two encounters with the product resulted in shouting from my part -- and just not working on the side of Data Integrator.
So -- I persisted.
A couple of weeks later, the product is becoming clearer. Projects contain Jobs (check) -- Jobs contain WorkFlows (check) WorkFlows contain DataFlows (check).
My conclusion so far — Data Integrator is not the easiest of products to use – but luckily, I succeeded in putting my hands on a good “core” tutorial pdf file…
