This course aims to teach students how to model object-oriented software by developing conceptual models, identifying classes and attributes, understanding associations, modeling events, defining invariants, and creating conceptual models. The course covers topics such as generalization relationships, abstract classes, multiplicity, and derived attributes. The teaching method involves theoretical explanations, practical examples, and class diagram creation. This course is intended for individuals interested in learning about object-oriented software modeling and design.
