Systems Analysis and Design

At the end of this course, students should be able to: 1. describe system requirements gathering techniques; 2. explain data modelling technique (entity relationship modelling); 3. explain process modelling technique (data flow diagram); 4. describe system architectural design; 5. describe process and database design; and 6. explain user interface design.

Structured approach to analysis and design of information systems for businesses. Software development life cycle. Structured top-down and bottom-up design. Dataflow diagramming. Entity relationship modelling. Computer aided software engineering. Input and output, prototyping design and validation. File and database design. Design of user interfaces. Comparison of structured and object-oriented design. Lab work: Practical exercises on software development life cycle (SDLC) activities with different case studies. Use of different information systems case studies to apply the knowledge of structured top-down and bottom –up design, dataflow diagram and entity relationship models.
