That's very useful to know. I have seen the experts, very useful. cheers Mark David – excellent, I hadn’t thought of that. That’s very useful to know.

I have seen the experts, very useful.

cheers

There is an isTime attribute on the AWXML dimension, if you have a quick look once you mark these descriptors the code generated by OWB will indicate a time dimension. Also in the AWXML the attributes will have a classification of END_DATE and TIME_SPAN. It might also be worth checking out an expert (create dimension from on exchange) which helps with building dimensions from existing tables which asks minimal questions and builds the dimension and its map/loader from a table/view/ext table. The simplicity of creating standard calculations in OWB saves a load of mundane work (time series analysis, share/index, rank etc.). Cheers David Hi Mark

The OLAP Application Developers’ Guide on OTN:

Are can suggest any book that will give how to start on olap, how to dimension, hierarchy and why and how and explain each step. Your help is greatly appericated. thanks, pvn i gone through your web site, it is good. i want to learn OLAP , i am a beginner,i am really struggling to understand the concept. is any article will give step and step example and explain each what each step mean.

I’m quite looking forward to this one - a bit like taking a tour around the world, then playing at home at the end - and as usual I’ll be adding a bit more content, this time around the slight difference in dimension and cube creation in OWB when you’re working against a multi-dimensional dataset. The seminar in the UK actually sold out a few weeks ago, and Oracle are therefore running a second event on November 23rd/24th which you can still book up for. Once the seminar is done, I’m preparing a one-day course for one of our University clients on building effective data warehouses using Oracle 10g, delivering it and then getting things sorted out for the UKOUG Conference in Birmingham the week after. The good thing is that this all means I’ll be UK-based for a few weeks, but it’s going to be a busy time and all very client-focused.
