Are there any sites to learn OLAP and Dundas easily and quickly?
Anywhere can I also see the source code. Like how the controls are interacting with db and how the Dundas charting controls are customized in backgroung code?
I'm not sure exactly what you're trying to do, but here's where I'd start if I was new to both concepts:
OLAP tutorial: http://training.inet.com/OLAP/home.htm and this: http://www.learndatamodeling.com/olap_analysis.htm
If you provide more details, you may get more specific results/direction.
Hope this helps!
