[School-of-data] BIG data... What is BIG?

[Julian Tait]

Hi Stefan,

I think the data that is being released by the National Health Service in the UK around prescribed medicines could be considered BIG - over 1GB per month, approx 4 million lines. http://www.hscic.gov.uk/searchcatalogue?productid=12419&topics=0%2fPrescribing&infotype=0%2fOpen+data&sort=Relevance&size=10&page=1#top with the potential to help solve BIG problems such as the prevalence of proprietary medication over generic - a big cost for the public health service or whether certain areas are anomalous in the way that anti-depressants are used etc.

Cheers

Julian
