Monday February 11th, 2013

A while ago I read an interesting paper by John Hauser, professor of Marketing at MIT Sloan School of Management titled, “Metrics: You Are What You Measure!” which he wrote jointly with Gerald Katz of Applied Marketing Science.

How to Compare Dual (Multi) Active System Data Warehouse Solutions

Thursday November 8th, 2012

Successful Enterprise Data Warehouses will and should evolve to a point where recoverability and availability requirements force the solution to jump over a technical chasm.  On the other side of this chasm lies the world of geographically remote active multi-system EDW infrastructures.
