The unified modeling language (UML) is a general-purpose visual modeling language that is intended to provide a standard way to visualize the design of a system. [1] UML provides a standard notation for many types of diagrams which can be roughly divided into three main groups: behavior diagrams, interaction diagrams, and structure diagrams.

统一建模语言（英語： Unified Modeling Language ，縮寫UML）是非专利的第三代建模和规约语言。UML是一种开放的方法，用于说明、可视化、构建和编写一个正在开发的、面向对象的、软件密集系统的制品的开放方法。

In software engineering, a class diagram [1] in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects.

uml是一種開放的方法，用於說明、視覺化、構建和編寫一個正在開發的、物件導向的、軟體密集系統的製品的開放方法。uml展現了一系列最佳工程實踐，這些最佳實踐在對大規模，複雜系統進行塑模方面，特別是在軟體架構層次已經被驗證有效。

UML建模時，一個實現（realization）關係是兩個模型元素之間的關係，其中一個模型元素（客戶端）實現的行為，其他模型元素（供應商）指定。 圖形以虛線和空心箭頭來表示。

uml代表了一系列在大型而复杂系统建模中被证明是成功的做法，是开发面向对象软件和软件开发过程中非常重要的一部分。uml主要使用图形符号来表示软件项目的设计，使用uml可以帮助项目团队沟通、探索潜在的设计和验证软件的架构设计。

Feel free to browse news and articles on UML, success stories, available certification and training, along with the current specifications. UML is OMG's most-used specification, and the way the world models not only application structure, behavior, and architecture, but also business process and data structure.

The Unified Modeling Language (UML) is a general-purpose, developmental, modeling language in the field of software engineering. UML is used to provide a standard way to show what the design of a system looks like.

Targets real-time or embedded systems and software using industry standard languages (UML, SysML, AUTOSAR, DoDAF, MODAF, UPDM, DDS), full production-quality code generation (structural, behavioral, functional), simulation, model based testing, integration with numerous real time operating systems and IDE's

In Unified Modeling Language (UML), a component diagram [1] depicts how components are wired together to form larger components or software systems. They are used to illustrate the structure of arbitrarily complex systems.
