And relax... Just finished the second of my twoDesktop Conference 2006 [http://www.desktopconference2006.org/]presentations, this time on Oracle OLAP Best Practices.

Keith Laker [http://oraclebi.blogspot.com/] from the Oracle Business Intelligence product team dropped me a line this evening, to tell me about a survey the Data Warehouse Development team at Oracle are carrying out. It sounds like a useful and interesting survey and I'll certainly be taking

Just a couple of updates. If you found the article last week on Oracle OLAP memory management useful, Chris Chiappa sent an email through to me this evening with some clarifications and corrections. I've annotated the article with Chris' comments and you canread the updated version here

I went to see a new customer last week who was looking to put together a company MIS system. The system needed to load and transform some data prior to analyzing it using OracleBI Discoverer, and to do the transformation they were looking at using OracleBI Warehouse Builder, and a

When you work with the OLAP functionality in Oracle Database 10g, you need to be aware of how it handles memory. Just like a relational data warehouse, data held in multidimensional datatypes makes use of memory structures such as the System Global Area [http://download-uk.oracle.com/docs/cd/B19306_

Just a quick one. If you came to theUKOUG BIRT SIG last week [http://www.rittman.net/archives/2006/01/ukoug_business_intelligence_re.html], and want to get hold of the Excel-based tool/sample Kevin showed us that creates calculated measures en-masse, it's now available for download

I just got in an hour or so ago after a week spent over in Ireland. As I mentioned the other day, I was due to do a bit of presales work with a public sector client, and I took the opportunity tospend the weekend in Belfast [http://static.flickr.

As the proposed Oracle purchase of Siebel draws closer [http://www.tmcnet.com/usubmit/2005/dec/1236475.htm], and Oracle announce that they're half way there to producing the first Fusion applications [http://www.informationweek.com/news/showArticle.jhtml?articleID=177102014], it's worth taking a look

I mentioned yesterday that I'm off to Ireland tomorrow, and the work I'm going to be doing for most of the week is a presales engagement for a public-sector organisation. It's probably true to say that presales is probably the sort of work that

I've got an interesting dilemma with a piece of consulting I'm doing this week. We're working with charity up in London who wants to add some Discoverer reporting to their OLTP application. They'd got licences for Discoverer but never got around to
