Prerequisites

Some experience of conventional systems analysis

Course Aim

To provide the student with some knowledge of and experience in using object-oriented methods in the systems analysis process

Learning Objectives

Point out the benefits of OOAD by comparing other models with object-oriented models. Contrast conventional methods with OO methods. Draw up a list of objects in a problem domain and write object descriptions for them. Identify classes and class responsibilities. Identify class methods and attributes. Create an object-messaging diagram. Distinguish the three major types of class relationships: generalization/specialization relationships; aggregate relationships; association relationships. Explain the concepts of inheritance and containment, and identify classes that inherit from each other. Draw up a class hierarchy diagram
