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。在分析了信息系统的不同类型描述和不同视角的呈现后，Zachman抛出了信息系统架构框架，这个框架图也是后续每每提到Zachman框架，引用最多的内容。
翻译中自己理解的东西加的比较多，不对的地方大家多多指正。
基本框架。目前为止，我们讨论了两个主要的观点：
The framework. Two ideas have been discussed thus far:
a. 在构建复杂的工程产品过程中，不同参与者从不同视角会产生一组不同的架构呈现。
a. There is a set of architecturalrepresentations produced over the process of building a complex engineeringproduct representing the different perspectives of the different participants.
b. 同一个产品，从不同目的出发，又会有不同类型的产品描述。
b. The same product can bedescribed, for different purposes, in different ways, resulting in differenttypes of descriptions.
结合以上两个观点，每一种不同类型的描述，会有不同参与者的视角呈现（或者说实际上是产品不同的呈现）。例如，原料（或数据）描述，会有所有者视角的呈现、设计者视角的呈现、建设者视角的呈现等；功能（或流程）描述，会有所有者视角的呈现、设计者视角的呈现、建设者视角的呈现等；对于位置（或地理）描述，同样会有所有者视角的呈现、设计者视角的呈现、建设者视角的呈现。
The combination of the two ideas suggeststhat for every different type of description, there are different perspectives(and actually different representations) for each of the different participants.For example, for the material (or data) description, there are the owner’srepresentation, the designer’s representation, the builder’s representation,etc. For the functional (or process) description, there are the owner’srepresentation, the designer’s representation, the builder’s representation,etc. For the location (or geographic) description, there are also the owner’srepresentation, the designer’s representation, the builder’s representation,etc.
图2说明了每种类型描述的不同视角呈现。需要注意的是，因为本文旨在描述信息系统架构框架，所以图2中使用的是表2、表3和表4中所有信息系统类比的概念，而不是更通俗的制造或生产概念。此外，表2中的机器运行视角也被省略了，仅仅从“架构”角度来描述，所以看起来不如其他领域的描述那么生动。
Figure 2 illustrates the total set ofdifferent perspectives for each type of description. Note that because theintent is to depict a framework for information systems architecture, all theinformation systems analog names from Tables 2, 3, and 4 have been used inFigure 2 in place of the more generic manufacturing or construction names.Also, the machine language perspective in Table 2 has been omitted, merelybecause it is not as interesting as the others from an “architectural” point ofview.

有趣的是，图2的矩阵中任一行上的内容都有别于其他行对应的内容，例如，业务模型（所有者的视角）不同于信息系统的模型（设计者的视角），等等。这里要注意的是，前面的讨论中已经讨论过，这些呈现不仅是细节的递进，而是完全不同的视角呈现——在内容、意义、动机、使用等方面都完全不同。同样，不同列上的内容也是有区别的，比如，数据描述的列（实体-关系-实体）不同于流程描述的列（输入-流程-输出），以此类推。无论从行来看还是从列来看，矩阵中每个元素都与其他元素明确不同，因此可以精确地定义每个单元格中的内容。
The one single factor that makes thisframework extremely interesting is the fact that each element on either axis ofthe matrix is explicitly differentiable from all other elements on that oneaxis. That is, the model of the business (owner’s perspective) is differentfrom the model of the information system (designer’s perspective), and so on.(Remember from earlier discussions that these representations are not merelysuccessive levels of increasing detail but are actually differentrepresentations-different in content, in meaning, in motivation, in use, etc.)Also, the data description column (entity-relationship-entity) is differentfrom the process description column (input-process-output), and so on. Becauseeach of the elements on either axis is explicitly different from the others, itis possible to define precisely what belongs in each cell, and further, eachcell in the matrix will be explicitly different from all the other cells.
