Models and modelling

Free Course Free Course

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.

After studying this course, you should be able to:

  • explain why modelling plays a key role in eliciting requirements
  • identify the different kinds of model used in eliciting requirements
  • explain the need for modelling languages
  • interpret a data flow diagram describing a simple process
  • interpret a use case diagram describing a system's response to a business event.

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.
