Subject: Re: [soa-rm-ra] OO vs. SOA and what goes into a service
I'm not talking implementation (SOA can use OO principles to develop the code) but general mindset. We once agreed that asking "what is a service?" is similar to asking "what is an object?" because the answer is it could be anything that fits your problem. My thought is a service is not necessarily a good object that you operate on but more like an operation that you may be feeding objects to. Again, this is all at the concept level, no implementation.

Assuming there is an object could be errant and architecturally un-elegant. ----------------------------------------------------------------------------- Ken Laskey MITRE Corporation, M/S H305 phone: 703-983-7934 7151 Colshire Drive fax: 703-983-1379 McLean VA 22102-7508 |
