RE: [ajug-members]: SOA Service Definition

["Brian Lee" <brian_a_lee@hotmail.com>]

yeah yeah, I've read all the blarg out there on SOA. I would like to find 
out the industry accepted definition of service. Does a service address a 
particular business function (like user management) and then provide 
operations (like createUser, modifyUser, moveUser, etc) or are the methods 
themselves the services?

My organization already has a definition of service, I'm trying to find out 
if it meshes with industry accepted jargon.

Thanks,
BAL
