I think we may be at cross purposes.
Big Data, to me, means datasets that are too large/complex/unstructured for conventional software systems to deal with.
For example I used to be involved with implementing software for financial trading platforms where we had to deal with intra-day pricing for thousands of global financial instruments, none of which had a standard universal identifier, and process the information “real-time” for the traders to trade. It’s fair to say I attended more than my fair share of conferences where Big Data was the theme. This, sadly, is time I will never get back
.
Anyway that’s what I’m thinking of when I hear the term “big data”.
The link you’ve sent is interesting, and I didn’t watch it all, but it seems to be a video of a 4th access (another word for rotary access) being used with a cnc mill to make pens.
I don’t see the connection.
Cheers
