Models and modelling
|
Learn about the importance of modelling in requirements elicitation and explore various diagramming techniques such as data flow diagrams and use case modelling. Enhance your understanding of system response with use case diagrams. Start your journey now!
Models are mechanisms for communication. This free course, Models and modelling, 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, entityrelationship diagrams and state machines.
