体系架构（Enterprise Architecture, EA）的开山之作，之前一直引用，从来没有系统的学习，通过翻译加深理解，与感兴趣的朋友一起学习探讨。继续展开说明第三列——网络（位置）的描述，对网络描述的业务呈现、信息系统呈现进行说明。

翻译中有一些是自己的理解，不对的地方大家多多指正。

业主在描述业务时，就产生了与网络相关联的架构模型（或着说业务之间的空间结构），这里“节点”呈现的是业务单元，是在某个地理位置的业务涉及资源（人员、设施、权责等）的集合。“连接”则代表物流和一些信息通信上的连接，但更重要的是呈现出连接发生物流或信息流的流向。

The owner, in describing the business, thatis, producing the model of the business as related to the network (or theconnectivity characteristics of the business), would perceive the “nodes” to bebusiness units, an aggregation of business resources (people, facilities,responsibilities, etc.) at some geographical location. The lines wouldrepresent logistics connections or flows, probably including communicationslinkages, but even more basically would represent the distribution structure orlogistics network along which communications take place.

在网络（位置）描述的信息系统架构模型（设计者视角）中，信息系统设计者将“节点”定义为某种I/S功能，如处理器、存储单元或网络接入点。这里是抽象的概念表示，不会像分解架构那样关联到特定的技术。从设计师的角度来看，“连接”是一条概念层面的通信线路，比如租赁线路、拨号服务等等。这一架构呈现将用于对系统“分布式”构建部署进行决策，即指定I/S设施将安装在哪里，哪些设备将被连接，以及使用哪类连接。

In the model of the information system (thedesigner’s perspective) for the network description, the information systemdesigner would perceive the node to be some I/S function, like a processor,storage unit, or access point. This would be a conceptual representation,independent of specific technology which would be introduced in the builder’scell. The line, from a designer’s standpoint, would be a communication line atthe conceptual level, such as a leased line, dial-up service, US. mail, etc.This cell would serve the purpose of making the “distributed systems”decisions, that is, specifying where the I/S facilities would be installed,which of them would be connected, and by what type of connection.
