Models and modelling

Description:

Models are mechanisms for communication. This course looks at what a model is and what the process of modelling is about. The techniques discussed here are applicable to a wide range of systems and have one thing in common: they are all commonly used diagramming techniques. The five techniques are: data flow diagrams, use case modelling, activity diagrams, entity–relationship diagrams and state machines. This OpenLearn course provides a sample of postgraduate study in Computing and ICT
