Terms such as superclass, subclass, or inheritance come to mind when thinking about the object-oriented approach. These distinctions are also used in model-driven development, where we have a succession of three types of models: Interfaces are model elements in UML modeling that define sets of operations that other model elements, such as classes or components, must implement. Usually, the class attributes are private, and the methods are public. This term is used in the software field. Class diagrams are most useful in illustrating relationships between classes and interfaces. Moreover, entity relationship diagrams help to design a database.
