The Pathologies of Big Data
There is an interesting article by Adam Jacobs in the new Communications of the ACM (Aug. 09, v.52, #8, pp. 36-44) on "The Pathologies of Big Data".
"Here’s the big truth about big data in traditional databases: it’s easier to get the data in than out."
"To achieve acceptable performance for highly order-dependent queries on truly large data, one must be willing to consider abandoning the purely relational database model for one that recognizes the concept of inherent ordering of data down to the implementation level."
