Structural Things

An artifact is a physical and replaceable part of a system that contains physical information (“bits”). In a system, you’ll encounter different kinds of deployment artifacts, such as source code files, executables, and scripts. An artifact typically represents the physical packaging of source or run-time information. Graphically, an artifact is rendered as a rectangle with the keyword <<artifact>> above the name.

工件是系统在物理上可替换的部分，包含了物理信息(“资料”). 在系统中，你会看到不同种类的部署工件，如源代码，可执行文件和脚本．工件最典型的表现是物理上的资源包或者是运行期间的信息．在图形表现上，工件由一个带有<<工件>>标识的长方形表示，在<工件>标识下方显示此工件的名称．

Anodeis a physical element that exists at run time and represents a computational resource, generally having at least some memory and, often, processing capability. A set of components may reside on a node and may also migrate from node to node. Graphically, a node is rendered as a cube, usually including only its name.

结点是系统运行时存在的物理元素，表示一个计算资源，一般至少有内存，有时也具有处理能力．组件集可能驻留在一个结点中，也可能从一个结点迁移到另一个结点．图形表示上，结点通常被表现为只包含一个名称的立方体，

These elements -- classes, interfaces, collaborations, use cases, active classes, components, artifacts, and nodes -- are the basic structural things that you may include in a UML model. There are also variations on these, such as actors, signals, and utilities (kinds of classes); processes and threads (kinds of active classes); and applications, documents, files, libraries, pages, and tables (kinds of artifacts).

类，接口，交互，用例，活动类，组件，工件和结点，这些元素是包含在UML模型中的最基本的架构元件．在这些元件基础之上还可以演变为其它的元件，诸如角色，信号，公共模块(类的种类)；过程和线程(活动类的种类)；应用，文档，文件，库，页，表(文件的种类)．
