A sample UML class and sequence diagram for the Strategy design pattern. [4]In the above UML class diagram, the Context class does not implement an algorithm directly. . Instead, Context refers to the Strategy interface for performing an algorithm (strategy.algorithm()), which makes Context independent of how an algorithm is impl
In UML, become is a keyword for a specific UML stereotype, and applies to a dependency (modeled as a dashed arrow). Become shows that the source modeling element (the arrow's tail) is transformed into the target modeling element (the arrow's head), while keeping some sort of identity, even though it may have changed values, state, or even class.
Examples of predefined UML stereotypes are Actor, Exception, Powertype and Utility. Structure diagram; Superstate - construct allowing several States which share common Transitions and Internal Activities; Swim lane - synonym for Partition; System model - The logical UML model being represented through one or more UML diagrams

A UML link is run-time relationship between instances of classifiers, while a dependency is a model-time relationship between definitions. A typical uni-directional link requires the one instance to know about, and thus depend, upon the other, but this is not required.

The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming.The builder pattern separates the construction of a complex object from its representation.
In short, MOF uses the notion of MOF::Classes (not to be confused with UML::Classes), as known from object orientation, to define concepts (model elements) on a metalayer. MOF may be used to define object-oriented metamodels (as UML for example) as well as non object-oriented metamodels (e.g. a Petri net or a Web Service metamodel).
