Read only versus Read/Write. Profile Servers, Product Servers, Query Services, and the like are information integration components that federate distributed, virtual data systems. They don't put any data back in. CAS not only reads from underlying data sources, and queries them, but it writes back into them too. > > So, if the query is first injected in a web-grid Profile Service? Not always, depends on how you entered the system, some folks go to CAS directly.
