After the flurry of articles around Open World, it's been pretty quiet around here for the past two weeks. Usually a lack of postings on the blog equates to very busy at work, and now I'm back I've been working away from home and

It was the final day of Open World today, and in actual fact it was probably the most productive (for me at least) in terms of BI & data warehousing content. I'll start off with one presentation that I missed, George Lumpkin's "Data Warehouse Architectures&

Well my bags are packed, and I'm off to SFO shortly to fly back to London. It's certainly been a memorable Open World for me, not so much in terms of new products or things learnt, more to do with the people I've met

Today was the day where I actually had to do some work, with an appearance down at the OTN Lounge and a podcast to record with Tom Parrish from DBAZine. Thankfully I didn't wake up with a hangover, but for the first time since I've been

A quick round up of a few odds and ends. I've had a few responses back now about the Open World bloggers' dinner, and it looks now like it won't be just me turning up, or indeed held in a phone box. So far the

I mentioned the other day that it might be an idea to have a bloggers dinner one night during Oracle Open World SF. A couple of people have come back and said that it might be worthwhile and therefore I'm offering to organise it. If any Oracle blogger
