How is the Unified Modeling Language ( UML ) used?
UML (Unified Modeling Language) is a graphical language for modeling the structure and behavior of object-oriented systems. UML is widely used in industry to design, develop and document complex software. This page will focus on creating UML class diagrams, which describe the internal structure of classes and relationships between classes.
How are objects and methods modeled in UML?
Often, objects and/or methods of one class use objects/methods from another class. For example, a person might read and/or own a book, and these relationships might be modeled in the UML diagram, so that they will be implemented in the corresponding program.
What is the basic notation for a class in UML?
