SAP Hana Spawns Virtual Data Warehouse

SAP's new Hana-powered In-Memory Data Fabric queries data without copying and stokes federated-access competition with IBM and Teradata.

SAP: Guinness Book Of World Records validates that SAP Hana-powered virtual data warehouse scaled to 12 petabytes and sustained sub-second query speeds.

Re: Avoiding pain and suffering
Doug, is this concept of a "logical data warehouse" or "information fabric" relatable to object-oriented storage? The two seem to have similar characteristics, and at some point, it seems like the "save everything" trend in enterprises will run smack into the desire to make every scrap of data available for analysis, so that the virtual data warehouse and the archive or tiered storage system become interdependent.

Avoiding pain and suffering
The logical data warehouse/information fabric concept is compelling because you avoid the ongoing pain of batch uploading and transforming data. Of course you still have a rigid database schema and you have to set up SAP's In-Memory Data Fabric to transform data in flight. And, as mentioned, you might have challenges tapping any old source if querying might create a performance hit. Long story short, we're still in the world of data warehousing here.

In my book anything in the neighborhood of petabyte league would be a candidate for a big data platform. I'm guessing a better play for virtual data warehouse would be a more focused use case involving smaller quantities of structured data -- and where near-real-time access to the latest data really matters.
