Comments/Suggestions: CPT 125 Pre-Requisite: Completion of 1st Year Courses Introduction: Systems Design is a central part of systems development. It comprises the process of turning a set of user requirements into an implementable system and encompasses various activities to achieve this end. Alternative models are challenging the traditional systems development life cycle. Alongside this, two approaches to systems development are emerging: the traditional structured approach; and the object oriented approach. The systems design activity will be studied in the context of these trends. Students should make themselves familiar with at least one traditional approach (e.g. SSADM) and one object oriented approach (e.g. UML). Aims: To understand the role of systems design within various systems development life cycles To develop awareness of the different approaches that may be taken to systems design To understand and apply the tools and techniques that are currently used by systems designers
