This is another Sam Newman conference talk, but I think a fairly good one. I’m passing it around for a couple reasons:
1. One of his principles focuses on Consumer Driven Contracts, and I couldn’t help but think of points of concern to Michael. Are there elements of a solution here?
2. Tight vs. loose coupling. In the SOA-RM, we basically said this was a red herring because it was a buzzword with no useful definition nor useful examples. Newman provides a good example.- Tight coupling: access data elements through use of s common (integration) database. To do this, everyone has to be exposed to all the implementation (e.g. schema) details.- Loose coupling: access data element(s) you want/need through an API without exposing implementation details (e.g. data elements for which you have no interest).
Talk with you on Wednesday.
