Characteristics of Domain Class
Domain classes in UML (Unified Modeling Language) have several characteristics that help define their structure and behavior. Here are some key characteristics of domain classes:
What is Domain Class in UML?
In UML (Unified Modeling Language), a domain class represents a concept or entity from the problem domain being modeled. It typically corresponds to a class in object-oriented programming and represents a real-world entity, such as a person, place, thing, or concept, that has attributes and behaviors.
- Domain classes are used to model the structure and behavior of objects in a system. They define the properties (attributes) that objects of the class possess and the operations (methods) that they can perform.
- Domain classes are often used to represent the core concepts and relationships in a system, providing a foundation for designing and implementing the system’s functionality.
In UML diagrams, domain classes are typically represented using class diagrams, which show the class name at the top, followed by its attributes and operations. Associations between classes can also be shown to represent relationships between entities in the problem domain.
