Programming Principles: Software Design

In this session we look at some of the basics of good code design, including avoiding duplication and designing for loose coupling and high cohesion.

System Design: Using UML Use Cases

In this lecture we cover how UML Use Cases can be used for requirements capture. We look at the anatomy of a Use Case Description, and the way in which use cases can be brought together in a use case diagram. We also look at the way that use cases can be derived from problems using noun verb analysis.

System Design: UML Activity and Sequence Diagrams

In this session we look at how to model flow of control and interactions between components using UML Activity and Sequence Diagrams. This is an introductory session and so for Activity Diagrams we only cover branching, forks and joins and swim lanes, and for Sequence we cover lifelines, messages and returns, and alt, par and opt frames.

System Design: UML Class Diagrams

In this session we look at UML Class Diagrams and how they fit into both the family of UML models, and also the software engineering process. We look at some basic features of class diagrams including properties, operations, associations, generalisation, aggregation and composition.
