Final Day at Collaborate

April 19th, 2007 by

Just a quick posting as I’m about to get my flight back to the UK (via San Francisco, unfortunately, so it’ll be a long journey). Yesterday I went to talks on SOA and RAC, and went along to Cary Millsap’s talk on why you often end up tuning the wrong thing when trying to optimize applications (tune the element that contributes most to response time, that sort of thing). Later on in the evening was the Collaborate’07 beach party, which I didn’t go along to for long as I had to get back to work on the Real-Time Decisions example, and because it was uncharacteristically cold and windy. Here’s a couple of photos:

And here’s Debra Lilley (UKOUG Director), Alvaro, Dimitri and John Scott.

Today I’m flying out around 1pm so I only had a chance to go to George Lumpkin’s talk on BI & Data Warehousing in 11g. Details are still fairly general at this stage, with the same coverage of partitining improvements, results cache and the like, but there were some new details on OWB and OLAP that are worth noting (with usual disclaimer about this being plans, not promises)

  • OWB11g will feature “Logical ETL Mappings”, where you can build a mapping and then set it as trickle-feed, or batch load
  • OWB will also at some point incorporate some of the heterogenous connectivity found in Sunopsis/Oracle Data Integrator
  • OWB will also start to embrace SOA – support for Web Services for example
  • For OLAP, the big thing in 11g will be making AWs behave more like Materialized Views. You’ll be able to tell AWM to place a layer over an AW to make it interchangeable with an MV, and to let it be refreshed like an MV
  • OLAP metadata (presumably ROLAP metadata currently in OLAPSYS) will move to the regular Oracle data dictionary
  • You’ll be able to tell AWM to aggregate cubes based on a cost-based scale (i.e. aggregate it 60%, or 30%, rather than selecting levels that you wish to pre-aggregate

There’s more to come on OLAP in 11g later in the year, I get the impression that the various product teams are still working through what’s going to be in this release and what’ll come along later. Once things are made official, I’ll post some blog articles on how the new features are going work out. For now though, I’m off to the airport to catch my flight to SF.

    If anyone is wondering why my neck looks broken in that picture it’s because the wind was so strong ;)

    Good to meet up with you again Mark (even for such a short time!), see at the next event no doubt!

    John.
