As a data warehousing/BI specialist I'd like to share my interperetation.
'Data' data (as in your company's data warehouse) is primarily internal data. By this I mean: data generated primarily by your source systems or associated business processes.
'Big' data is external data. It is tweets that express opinion about your brand. Weather patterns that might influence supply logistics. Demographics of markets you wish to penetrate.
I think there are a great number of slightly different interpretations out there but pragmatically speaking, what I have suggested here makes sense.
- ironchef 13y agoI think that _can_ be a starting point; however, there are definitely cases where it's not the case. Take ebay or facebook for example. I'm pretty sure their "data" data is "big" data...would you concur? I think the external data increases the variety (naturally) as well as has some effect (depending on the sources) on the volume and velocity of said data....thusly pushing it over the edge from "data" data to "big" data potentially.
- mark_integerdsv 13y ago>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.
