In the context of data modeling, what does the term 'class' refer to?

In data modeling, the term 'class' typically refers to an entity that encapsulates both the data and the relationships associated with that data. A class is essentially a blueprint for creating objects, and it contains attributes (which define the properties or characteristics of the class) and methods (which define the behavior of the objects created from the class).

When discussing options, the notion of a class as an entity with attributes highlights the structure and organization of data within a system. Attributes are essential for defining the data specific to that class, allowing for the distinction and interaction of different entities within a model. This aligns with concepts used in object-oriented design, where classes serve as foundational components for organizing and managing data.

Understanding a class this way is crucial for accurately constructing data models that effectively represent real-world entities and their interactions within software applications.
