Awesome idea, Pi!
Bottom line: sooner or later somebody is going to package up a "olap-

Has anyone ever looked at OLAP Cube processing on Pig or
MapReduce? This
feature should be beneficial for normal businesses (probably not web

relational
abstraction (but might not scale well on really big datasets). I
have done a
sketch on how I think it should look like here
