Move part of the bi services into the framework? move the bi component into the framework? or for now, since the code there is since a prototype, keep everything into bi (as is now) and postpone this re-factoring?I'm a big fan of having BI stuff in the framework, like general ETL tools (as much as that applies, and I know those are based on other framework tools) and the ad-hoc reporting web pages based on the star schema tables desired (which is really cool).The only think I can think of that might be funny is in the ad-hoc reporting tool if it was in the framework we wouldn't want application specific stuff in it. We may end up wanting to have the BI tools in the framework, the ETL implementations per applications component in that component, and a big ad-hoc reporting app that builds on all of that stuff. Of course, maybe that could be data driven too and like in the framework and it wouldn't be a problem.
David, I can confirm that the existing simple reporting application in the BI component is meta-data driven, no application specific stuff is in it. so that wouldn't be an issue. Or maybe we could just move the screens from the BI application to the Webtools, and move the bi component (without webapp) to the framework.
What do you think? Jacopo
Anyway, just some thoughts. I do like the framework idea though. -David
