>would you concur? I see what you're driving at and I don't disagree but I bet both Ebay and Facebook have a bit of data in a ruddy old fact/dimension warehouse and some neat dashboards and reports over the top of it. In which case I'd stick with my definition and simply state that in these examples, they have both types of data. I just realised I know zero about the infrastructure of either of those businesses so I have some reading to do... oh, and everything I said about them might be crap.
