Then, the modeling method of GDCN was analyzed, and the effective modeling method of the domain constraints based on simulation and Meta modeling was presented.
对GDCN的建模技术进行分析后，提出了基于仿真分析和元模型技术的领域级约束建模的有效方法。
The reason is that these details depend on implementation and deployment domain decisions and constraints.
其原因就在于这些细节依靠执行和配置域的决定和约束。
You can sometimes predict complexity based on speculative knowledge of the problem domain, but writing code creates new constraints and opportunities that are virtually impossible to predict.
有时候可以根据问题域的理论知识预测复杂性，但是在编写代码时，又会产生新的约束和机会，这些实际上是无法预测的。
For example, in what I'll call a DSA, the strong domain model falls away in favor of events, which has certain constraints, and context becomes a much more fluid idea.
例如，在我称为DSA的软件架构中，强领域模型更倾向于事件，它具有某种约束，上下文则成为一种更易变的概念。
And each domain has its own set of rules and regulations that put constraints on data.
而每个领域都有自己的一套约束数据的规则和规范。
By convention, Grails looks for a script with the same name as your domain class but ending with the word "Constraints" (e.g., EmployeeBeanConstraints.groovy).
根据惯例，Grails以领域类名+“Constraints”为名字(如employeebeanconstraints .groovy)，去查找脚本。
The constraints are defined in the bean (domain object) so the validation logic is close to the domain model.
约束是定义在一个bean（领域对象）中的，因此校验逻辑离领域模型最近。
Grails looks for the constraints declarations in the same directory as our domain class.
Grails在领域类相同的目录下查找约束声明。
Constraints: While facts describe relationships between types within the business domain, constraints describe limitations in that domain.
约束：事实描述业务领域中不同类型之间的关系，而约束(constraints)则描述那个领域中的限制。
Because it would launch the container, including the SSH daemon, in the unconfined_t domain, giving him a privileged shell and allowing him to escape the SELinux constraints we were trying to enforce.
因为它会在unconfined _ t域中启动容器，包括sshdaemon，这使他能够获得有特权的shell，并且能够绕过我们将要实施的SELinux限制。
First, a business-level analysis class is one that is essential to the business domain, without reference to implementation or technology constraints.
首先，一个业务级别的分析类是业务领域中的一个要素，与实现技术无关。
But the trend toward each child having their own domain may be changing due to economic constraints.
但是，由于经济形势窘迫，这种让每个孩子拥有自己领地的潮流或许将发生改变。
I'm used to adding static constraints blocks to my domain classes, so adding a static mapping block feels consistent with the rest of the framework.
我习惯将静态constraints块添加到域类，这样添加静态mapping块感觉起来和添加框架的其余部分是一致的。
This will ensure that the development remains within any limiting circumstances (such as legal constraints or domain standards). Following are two examples of constraints.
这样可以确保在人任何限制环境下开发可以继续进行(比如法定限制或者范围标准)。
Design attribute domain integrity. Considerations include CHECK constraints, data types, and nullability.
设计域完整性属性。考虑CHECK约束，数据类型和是否非空。
This is where you can put the static constraints block that would normally be in the domain class.
该文件中可以放置本应该位于域类中的静态constraints块。
Understanding business, technical, and domain opportunities, requirements, and constraints.
理解商业、技术，以及业内的机会、需求和制约。
Qualitative research helps us understand the domain, context, and constraints of a product in different, more useful ways than quantitative research does.
与定量研究相比，定性研究以另一种更有用的方式帮助我们理解产品的问题域、情境和约束条件。
