WHY THE DATA WAREHOUSE IS BACK (AND WHY IT NEVER REALLY WENT AWAY)

The rise in Enterprise data volumes and the increasing use of semi-structured data gave rise to Big Data and NoSQL platforms. But the conventional data warehousing model never went away.  And with innovations in cloud object storage and compute capabilities, the data warehouse model has come out of the shadows and back into the spotlight.Data silos were a problem even in the old days, but the challenge they pose today is acute.  Some organizations, still wary of older storage costs and cost models, are conservative in the data they preserve.  Others tend towards the opposite extreme, saving data in cloud object storage with such abandon that they engender impenetrable repositories that form huge silos of their own.
