UML：统一建模语言 (UML: Unified Modeling Language)

UML is an abbreviation of Unified Modeling Language. In the field of software engineering, it is a visual modeling language that is standard in quality. It makes it available to use an excellent way to visualize the blueprint of a system. It is projected to be used for examination, design, and execution of software-based systems, modeling business, and related processes. The primary model of UML was created by Grady Booch, Ivar Jacobson, and Jim Rumbaugh. In June 2015, its recent model UML 2.5 is launched.

UML是Unified Modeling Language的缩写 。 在软件工程领域，它是一种视觉建模语言，在质量上是标准的。 它使得可以使用一种出色的方法来可视化系统的蓝图。 预计将用于基于软件的系统的检查，设计和执行，业务建模以及相关流程。 UML的主要模型是由Grady Booch ， Ivar Jacobson和Jim Rumbaugh创建的 。 2015年6月，推出了其最新型号UML 2.5。

In 1997, UML was developed as a standard by the Object Management Group (OMG). In 2005 as an official ISO standard, it was prepared and issued by the International Organization for Standardization (ISO). From that particular time, it is revised from time to time to cover the most recent alteration of UML.

1997年，对象管理组(OMG)将UML作为标准开发。 作为国际标准化组织的官方标准，该标准于2005年由国际标准化组织(ISO)制定和发布。 从那个特定的时间开始，不时对其进行修订，以涵盖UML的最新更改。

The objective of UML, according to Object Management Group is as follows,

根据对象管理小组的说法，UML的目标如下：

• To make available for use the system architects and software engineers a tool for examination, design, and execution of software-based systems and related processes.

  为了使系统架构师和软件工程师可以使用的工具，该工具可以检查，设计和执行基于软件的系统和相关过程。

• To move ahead through object visual modeling means interoperability, the position of the industry.

  通过对象视觉建模前进意味着互操作性，即行业的地位。

In comparison to other programming languages such as Java, C++, and COBOL, etc., UML is dissimilar. It is an illustrative language that is used to make designs of software. To explain, indicate and document the obtainable or new business processes and configuration and activities of artifacts of software systems, it is generally used by business analysts, software architects, and developers.

与其他编程语言(例如Java，C ++和COBOL等)相比，UML有所不同。 它是一种用于设计软件的说明性语言。 为了解释，指示和记录可获取的或新的业务流程以及软件系统工件的配置和活动，业务分析师，软件架构师和开发人员通常使用它。

Additionally, UML can be useful to numerous application domains such as banking, internet, healthcare, aerospace, etc. It can also be used with software development techniques and for several execution platforms such as J2EE, .NET.

此外，UML可以用于众多应用程序领域，例如银行，互联网，医疗保健，航空航天等。它还可以与软件开发技术一起使用，并可以用于多个执行平台，例如J2EE，.NET。

优点 (Advantages)

• In a computer program, a UML diagram is a visual description of the associations between classes and entities.

  在计算机程序中，UML图是类和实体之间关联的直观描述。

• A UML diagram is readable which makes it very useful.

  UML图是可读的，因此非常有用。

• In object-oriented programming languages, UML is the contemporary standard for programming.

  在面向对象的编程语言中，UML是当今的编程标准。

• Before the programming takes place, UML aids to design a program.

  在进行编程之前，UML有助于设计程序。

缺点 (Disadvantages)

• Managing and maintaining UML diagrams by using UML is a time taking process.

  使用UML管理和维护UML图是一个耗时的过程。

• Software developers operate with code, not images or diagrams which makes UML not advantageous to them generally.

  软件开发人员使用代码而不是图像或图表进行操作，这使得UML通常不利于他们。

• In a UML diagram, inspecting a scope of software can lead to software project stakeholders over-examining issues.

  在UML图中，检查软件范围可能导致软件项目涉众过度检查问题。

• It leads people to drop the center of attention by spending lots of time and attention on software specifications.

  它通过花费大量时间和精力在软件规范上，使人们失去了关注的中心。
