Data Virtualization Series Part 1 – What is it?

We have all heard of data federation and of late we have also been hearing how simple, traditional data federation often gets passed off as data virtualization. Let’s get back to basics and take a hard look at what the real need is.

TDWI’s Wayne Eckerson does a great job at tracking the evolution of data federation in his recent webinar and blog.
