The term "process model" seems to have raised a lot of questions, and not to have conveyed what I intended to convey.
Here's an example that illustrates, roughly, what I mean by a "process model". This is a brief quote from "Object Oriented Analysis" by Coad and
Yourdon."The underlying strategy of functional decomposition consists of selecting the processing steps and sub-steps anticipated for a new system. Analysts use previous experience from similar systems, combined at times with an examination of required outputs. The focus is on what processing is required for the new system. The analyst then specifieas the processing and functional interfaces."
As far as I can tell, functional decomposition results in a process model.
Every information system I've dealt with was, at some stage of its development, described by a process model and a data model. Sometimes these models were implicit and non verbalized, but they were models nonetheless. Received on Fri May 19 2006 - 13:22:46 CEST
