I had unexpected discussion on how many interfaces one SOA Service may have. In my opinion, a SOA Service may have one or more interfaces. What would you say?...

The challenge comes from how much you want to separate interface from implementation in your definition of service. For example sake, let's suppose we're...
Correct me if am wrong: Two points that you have highlighted are: 1. Contract is meant to reduce the dependency between consumers and providers. 2. Contract...
