Models and modelling

The course covers various aspects of models and modeling, including types of models, modeling languages, data flow diagrams, diagramming techniques, use cases, activity diagrams, entity-relationship data modeling, and state machines. By the end of the course, learners will be able to create consistent models using different techniques, understand the relationships between use cases, and develop entity-relationship data models. The teaching method includes theoretical explanations, examples, exercises, and self-assessment questions. This course is intended for individuals interested in learning about modeling concepts and techniques in the context of information systems or software development.
