For neady ten years,the Unified Modeling Language(UML)has been the industry standardfor visualizing,specifying,constructing,and documenting the【S1】of a software-intensivesystem.As the【S2】standard modeling language,the UML facilitates communication andreduces confusion among project【S3】.The recent standardization of UML 2.0 has furtherextended the language’s scope and viability.Its inherent expressiveness allows users to【S4】everything from enterprise information systems and distributed Web·-based applications to real-timeembedded systems.The UML is not limited to modeling software.In fact,it is expressive enough to model【S5】systems,such as workflow in the legal system,the structure and behavior. of a patienthealthcare system,software engineering in aircraft combat systems,and the design of hardware.To understand the UML,you need to form. a conceptual model of the language,and this re—quires learning three major elements:the UML's basic building blocks,the rules that dictate howthose building blocks may be put together,and some common mechanisms that apply throughout theUML.

It should go without saying that the focus of UML is modeling. However, what that means, exactly, can be an open-ended question.(71)is a means to capture ideas, relationships, decisions, and requirements in a well-defined notation that can be applied to many different domains. Modeling not only means different things to different people, but also it can use different pieces of UML depending on what you are trying to convey. In general, a UML model is made up of one or more(72)A diagram graphically represents things, and the relationships between these things. These(73)can be representations of real-world objects, pure software constructs, or a description of the behavior. of some other objects. It is common for an individual thing to show up on multiple diagrams; each diagram represents a particular interest, or view, of the thing being modeled. UML 2.0 divides diagrams into two categories: structural diagrams and behavioral diagrams.(74)are used to capture the physical organization of the things in your system, i.e., how one object relates to another.(75)focus on the behavior. of elements in a system. For example, you can use behavioral diagrams to capture requirements, operations, and internal state changes for elements.
