轻量级设计模式使您可以在对象和集成服务之间进行松散耦合，而无需艰苦地编写业务逻辑或领域模型。
Identified defects may potentially need to be resolved in the model, in the manually developed business logic code, the model transformations, or some combination of these.
已确认的缺陷可能需要在模型中解决，在人工开发的业务逻辑代码中，要在模型转换，或它们的组合中解决。
The model class holds the essential business logic and manages the data corresponding to that part of the application.
模型类存放实际的业务逻辑，并管理与应用程序部分对应的数据。
The SOA programming model also needs a unified paradigm for creating and accessing business logic.
SOA编程模型同样需要统一的范型来创建和访问业务逻辑。
This paper defines a model of the timeline pattern and its behavior, and describes methods for encapsulating the timeline model and logic as reusable smart components.
本文定义了一个时间轴模式的模型及其行为，并描述了几种用于将该模型及其逻辑封装为可重用的智能组件的方法。
Much of the expressiveness comes from there being tags for conditional logic, dynamically changing the input model, and controlling the flow of execution.
表现力大多源于存在条件逻辑、动态更改输入模型和控制执行流的标签。
Most custom sweepers observe some model object, and based on changes, fire logic to expire one or more cache pages.
多数定制清理器都会观察某些模型对象，并根据更改击发逻辑来使一个或多个缓存页面到期失效。

应用程序的业务逻辑使用包装器api直接操作xml模型。
As you see, with the current implementation, there is no way to transform the UML model into COBOL business logic; it is a very database-oriented kind of transformation.
如您所见，使用当前的实现，我们无法将uml模型转换为COBOL业务逻辑；这是一种面向数据库的转换。
An application's reliance on XML documents for data exchange and relational databases for data persistence are characteristics of the application's business logic (that is, its model).
应用程序依赖XML文件来进行数据交换以及关系数据库来提供数据永久性都是应用程序业务逻辑(也就是其模式)的特征。
