How old is your data warehouse? It’s a simple question and probably one you don’t think about much.

It’s starting to feel its age as more Business Intelligence requirements have been added, including Mobile applications and specialized analytics. And more and more ideas seem to show up in your inbox every day, especially Big Data questions.
