My second tutorial for today is Building Open Source Data Warehouses by John Paul Ashenfelter. I'm not entirely sure how relevant this is going to be as he seems to be pitching heavily towards the industry guys, and putting things in their terms, however since just about all of the backend databases in the Astronomy community are data warehouses rather than the more common transactional style databases, I should be able to get something out of this...
Update: I'm about an hour into the tutorial, and I'm a bit worried as John seems to be giving a talk about data warehousing rather than giving a tutorial. The two things are very different and I'm not entirely sure he understands this...
Update: I'm not getting as much out of this as I hoped, I usually get one busted tutorial out of the four at OSCON, I guess this is this years. Pity, but tomorrow I've got Mark-Jason Dominus talking about Making Programs Faster and Alex Russell talking about Learning Ajax. They should both be good, looking forward to them...
