Enterprise Architecture[企业架构]
(Zachman)

知识中心

早在1987年，John Zachman就提出： “为了避免企业分崩离析，信息系统架构已经不再是一个可有可无的选择，而是企业的必需”。 从那时起，Zachman的企业架构理论就开始逐渐发展起来， 它现已成为许多大公司用来理解、表述企业信息基础设施的一个直观模型， 为企业现在的以及未来的信息基础设施建设提供了蓝图和架构。

Zachman的企业架构是一个全新的模型，为企业信息基础设施提供一种可以理解的信息表述。
Zachman没有把企业的流程简单视作一系列步骤，而是综合考虑不同角色的不同观点，提出了一个多视角、多维度的企业架构。

企业架构中的不同角色

1. 企业拥有者。
2. 业务管理者。
3. 系统分析者。
4. 系统设计者。
5. 系统建设者。
6. 系统本身。

下图的各行内容即反映了不同角色的不同关注点（角度）。
Zachman同时承认每个角色均关注相同的信息类别（维度），即下图各列内容。

企业架构的信息类别

• 数据（什么？）
• 功能（怎样？）
• 网络（哪里？）
• 时间（何时？）
• 角色（谁？）
• 动机（为何？）

企业架构理论术语

• “企业”（Enterprise）是指由一整套可识别的、互为作用的业务功能构成的商业组织。 它有能力作为独立实体经营运作。 根据这一定义，就应该存在企业内的企业。 只要企业内部的事业部门能够独立运作，它或许就可以被当作一个企业。 在这里，这一企业概念也可以被看作为“扩展企业”（Extended Enterprise），它意味着企业架构框架也包括了企业与外部实体的相互关系。 例如： 供应商、商业伙伴和客户。
• “架构”（Architecture）提供基础框架， 它定义和描述了企业实现经营目的和商业愿景的平台。 “架构”可以被具体定义为： 与企业经营战略、信息需求紧密相连的一整套原则、方针、政策、模型、标准以及流程，它结合企业未来发展方向，为企业各项解决方案的设计、选择和执行提供指导。
