You're getting dangerously close to my favorite design approach - which really starts with requirements elicitation - namely, Ian Graham's SOMA method(ology). He advocates considering the system as interacting with people (or other computer systems) via a series of (abstract) messages. The messages convey some data and a request, the return provides data or confirmation or whatever. It is the responsibility of various tasks to accomplish the golas of the messages. These tasks may - or may not - end up getting implemented by some set of objects in the O-O sense. This could tie in to your earlier post in that a person asks the system for certain data (reports) - that might when generalized become a requirement. Cheers, Tom P
