SQL and NoSQL are Two Sides of the Same Coin

[sl4shd0t]

An anonymous reader writes "NoSQL databases have become a hot topic with their promise to solve the problem of distilling valuable information and business insight from big data in a scalable and programmer-friendly way. Microsoft researchers Erik Meijer and Gavin Bierman ... present a mathematical model and standardized query language that could be used to unify SQL and NoSQL data models." Unify is not quite correct; the article shows that relational SQL and key-value NoSQL models are mathematically dual, and provides a monadic query language for what they have coined coSQL.http://a.fsdn.com/sd/facebook_icon_large.png (http://www.facebook.com/sharer.php?u=http%3A%2F%2Fdevelopers.slashdot.org% 2Fstory%2F11%2F04%2F07%2F2053219%2FSQL-and-NoSQL-are-Two-Sides-of-the-Same-Coin%3Futm_source%3Dslashdot%26utm_medium%3Dfacebo ok) http://a.fsdn.com/sd/twitter_icon_large.png (http://twitter.com/home?status=SQL+and+NoSQL+are+Two+Sides+of+the+Sam e+Coin%3A+http%3A%2F%2Fbit.ly%2FgsN3On)
