本系列的第4部分概述了SOA中概念数据建模和逻辑数据建模的作用。
Part 4 in this series Outlines the role of conceptual and logical data modeling within SOA.
考虑到在GSA企业架构中这种工具所起到的重大作用，本小节将对逻辑或物理数据模型如何被转换至eaml做一个概括性的介绍。
Given the important role this tool plays in the GSA's enterprise architecture, this section provides an overview of how logical and physical data models have been transformed to EAML.
评价和论证意味着检验文章逻辑的可靠性和感情的作用。
Evaluating an argument means testing the logic of a text as well as its credibility and emotional impact.
该层的作用在于针对不同的数据存储技术，从业务逻辑中分离数据访问代码。
The power of this layer is in separating data access code from the business logic for disparate data store technologies.
在数学学科的很多的领域中算术只是起到次要作用，例如逻辑学和几何学。
There are entire fields of mathematics where numerical manipulation is peripheral: logic and geometry, for example.
量子逻辑可能更加适合起作用的决定，尽管这些决定不是逻辑完美无缺的。
Quantum logic may be more suitable to making decisions that work well enough, even if they're not logically faultless.
不过，至少就他们的衣着而言，起作用的其实并非逻辑而是迷信。
As it turns out, however, at least when it comes to their clothing, superstition rather than logic rules.
该技术也鼓励良好的模块化，这最小化了可视元素和作用于这些元素之上的应用程序逻辑之间的耦合。
The technique also encourages good modularization which minimizes the coupling between visual elements and the application logic which ACTS on them.
最后，我们希望业务逻辑在EIS中能发挥神奇的作用，而无需知道它的原理。
In the end, we would like our business logic to live in blissful ignorance of the scary magic in the EIS.
通过这些文件中的注释了解代码的作用，或者参考下一节中对代码逻辑的解释。
Review the comments in these files to understand the code or refer to the next section, which provides a high-level description about the code logic.

作为迁移工作的一部分(这对确定垂直部分的作用域来说最是如此)，应用程序的业务逻辑不应改变。
As part of a migration effort (and this is most certainly true for the scoping vertical slice), the business logic of the application should not change.
然而，让我们把目光从单一的理论叙述移到理论论证上(像“所有男人都很高，佛瑞得是个男人，因此佛瑞得很高”)时，这种逻辑的作用就显而易见了。
However, when we look not just at single rational statements, but at rational arguments (such as' all men are tall, Fred is a man, therefore Fred is tall ') we can see that the logic is useful.
而经验是建立在试验和统计的基础上，在某些方面有可能做得不一定非常准确，但其逻辑是可以进行调整，没有用的药或者副作用大的药会被取消，或者被减量，这就是试错。
The experience depends on clinic experiments and statistics, which though not absolutely precise can also perfect itself by canceling non effective or harmful side effect herbs.
选择文件的作用域时，务必要考虑Web站点的统计和逻辑访问组件。
When choosing how to score your files, consider the statistical and logical access components of your Web site.
LinuxLVM实现了一种称为快照(Snapshot)的特性，它的作用就像是“拍摄”逻辑卷在某一时刻的照片。
Linux LVM implements a feature called Snapshots that does exactly what the name says: It's like taking a picture of a logical volume at a given moment in time.
从职业的角度来看，仅关注数据库和业务逻辑的WebV1.0时代的“后端工程师”，在WebV2.0时代中作用是有限的。
From a career perspective, the "back-end engineers" of the Web V1.0 world, who focused just on the database and the business logic, are limited in the Web V2.0 world.
不需要将连接性逻辑重新部署到基础结构中，因为它们全都在注册中心进行了描述，并以近实时的方式发挥作用。
There is no need to redeploy the connectivity logic into the infrastructure, as it is all described in the registry, and acted upon in near real-time.
因为与扑克筹码有关的联结,是通过经典条件作用建立的，所以按照这种逻辑,扑克筹码迟早会失去强化物的作用。
Since the connection with the poker chips is established through classical conditioning, sooner or later by that logic the poker chips would lose their power to serve as reinforcers.
在这一层级上，我们创建逻辑元素、分发元素和系统功能性的收集，并且对它们的交互作用进行建模。
In this level, we create logical elements, distribution elements, and collections of system functionality, and we model their interactions.
如图2所示，决策表在指定，分析和测试复杂逻辑性时起到很重要的作用。
As illustrated in Figure 2, decision tables are useful when specifying, analyzing, and testing complex logic.
故事板就是特定情景中对系统逻辑和概念上的描述，包括系统用户与系统之间交互作用的需求。
A storyboard is a logical and conceptual description of system functionality for a specific scenario, including the interaction required between the system users and the system.
先读取技巧涉及重构（或编写）应用程序逻辑和工作流，以便所有的处理和读取操作在事务作用域的外部首先发生。
The read-first technique involves refactoring (or writing) the application logic and workflow so that all processing and read operations occur first, outside of a transaction's scope.
然而，同样的逻辑不能用于改善社会上的相互作用。
However, the same reasoning cannot be applied to improving social interaction.
但是，如果逻辑中包含真实的业务值，就会想到测试它，这个时候就可以看到提取方法模式的作用了。
If that logic embodies true business value, however, then you'll want to test it, in which case you'll get to see the Extract Method pattern at work.
那些逻辑日志缓冲区以循环方式起作用，以确保将获得的每一条逻辑日志记录都被刷新到磁盘中。
Those logical-log buffers are operating in the circular manner to ensure every logical log record got is flushed to disk.
因此，与AND逻辑不同，使用OR逻辑时，需要将过滤作用较弱的谓词编码在过滤作用较强的谓词之前。
Therefore, unlike AND logic, with or logic we want to code the least-filtering predicate before the most-filtering predicate.
而经验是建立在试验和统计的基础上，在某些方面有可能做得不一定非常准确，但其逻辑是可以进行调整，没有用的药或者副作用大的药会被取消，或者被减量，这就是试错。
Therefore it is not definitely right on some aspects. Mistake test is to adjust its logics by canceling or reducing the dose of useless medicine or that of severe side-effects.
尽管，理论上在有可能在一个单独的组件上封装这些逻辑，以便被多个服务重用，但是实际上几乎不起作用。
Although, theoretically, it is possible to encapsulate such logic in a separate component, reusable by multiple services, in practice it rarely works.
