Peter Coad's design approach (which ZPatterns is heavily based on/biased towards) emphasizes four major layers of classes in an application:
1) User Interface (GUI, forms, etc.) 2) Problem Domain (the actual application purpose) 3) Data Management (object persistence/lifecycle management) 4) System Interaction (interfaces w/hardware or other software)
Is this from one of his books? If so, which one? I would be interested in gaining more enlightenment. :) Thanks, Jimmie Houchin
