You’ve read about the ADF Methodology Group that was founded for the masses and the group is still growing and the topics are evolving.
More information regarding the ADF Methodology can be found on the Oracle wiki page.
Today I’ve added some content regarding a definition on ADF Taskflows, BPM, UML, BPEL, etc. and especially for which purpose these technologies can be used.
On the wiki-page you will find more information regarding when and why I would use these kinds of methodologies and the benefits or drawbacks I find when using them.
Feel free to add comment, add suggestions, add your own approach, etc. Looking forward for new ideas!
That said aside, our Google group is also worth reading in the meantime, you can check it out here.
