RMO CSMS PROJECT DOMAIN MODEL CLASS DIAGRAMS

Systems Analysis and Design in a Changing World, 6th Edition 42

 There are several ways to create the domain model class

diagram for a project

 RMO CSMS has 27 domain classes overall

 Can create one domain model class diagram per subsystem

for those working on a subsystem

 Can create one overall domain model class diagram to

provide an overview of the whole system

 Usually in early iterations, an initial draft of the domain

model class diagram is completed to guide development

and kept up to date
