Biggest Database in the UK?

[NotAGolf]

Any idea as to who has the biggest database in the UK? (With regard to the number of different people stored on it). I've googled but to no avail. Someone has suggested Barclays with around 3/4 million people. Is this true?

Thanks.

Well i'm doing an assignment and its about the new NHS Care Record System. Thats going to be around 50-60 million when finished, and according to my lecturer that's going to be the biggest, and by a a long way. (In the UK anyway).

I was just trying to find out how much "by a long way" is.

**edit:** actually thinking about it he was the one that mentioned Barclays is the second biggest, how could he miss something as obvious as HMRC or Tesco?? Is there something I'm missing here?

Hmm, yea I see that there's a lot larger one's that you've suggested.

Maybe it's got to be something to do with how it's used, i.e. updated and altered by any member of staff anywhere in the country at any time?

I'll have to ask him next lecture.

Thanks for all the replies as well.
