Course Overview

The course presents object oriented (OO) analysis and design. The OO analysis and design stages are looked at separately and the differences explained. Participants are taught to look at objects with care, while design considerations and principles in choosing classes are explained. Design principles are presented in detail.
Since the participants are assumed to have basic OO knowledge, object oriented concepts are only briefly explained – to “fill in the holes”.  UML class diagrams are introduced, as are CRC cards, including holding a CRC workshop session.  Interactive examples are used to encourage the development of OO analysis and design skills.

Who should attend?

Analysts, designers and programmers who need to use object oriented analysis and design techniques.

Prerequisite:

Some knowledge of Object Oriented programming and/or design is required.
