The cool stuff: enterprise IT groups are now moving beyond the 1990s model of structured data warehouses, and now are starting to think in terms of more accessible and cost-effective "data lakes": vast repositories that are landing zones for any and all enterprise data that might potentially be interesting in the future.
The motivations are clear: information is the new asset, and its value can only increase when new uses are found. Yes, applications still "own" their information, but it's also an asset that's owned by the organization at large. Data lakes hold the promise of making it far easier to span organizational and temporal boundaries and harvest all that latent analytical goodness.
But, as in any valuable shared asset, it's going to need to be managed: what goes in, what comes out -- and who can play.
And when new important roles emerge, technology innovation is not far behind.
