A sample from this course

One topic, as StudyPath teaches it.

Object-oriented data models

Object‑oriented data models (OODMs) describe data in terms of objects that encapsulate state and behaviour, mirroring real‑world entities. Mastering classes, objects, inheritance, polymorphism, encapsulation, and abstraction is essential for modelling complex systems and for translating OODMs into relational schemas during database design.
