Hi, I wonder if there are any best practices, white papers, articles etc available for how to design data interaction between components? I have read "Workflow data patterns" by van der Aalst but it does not discuss how to design the components so that they will be loosly coupled in terms of data dependencies. I have read a couple of articles about canonical data models aswell, but usually on a too abstract level to really be of any use to me. Any advice would be appreciated. thanks, -Kristoffer View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4062150#...
