DSL工具
You can use a domain-specific language for a specific task in a fixed-problem domain.
在一个确定的问题领域中，你可以为一个特定的任务使用DSL。
This makes it different from a general-purpose language.
这使得它与通常目的语言不同。
By using Domain-Specific Language Tools, you can build customized modeling tools.
通过使用DSL工具，你能够创建自定义的建模工具。
You can define a modeling language and implement it very simply.
你能够定义一个建模语言,并能够非常简单的实现它。
For example, you can create a specialized language that describes a user interface, a business process, a database, or the flow of information.
例如，你能够创建一个用于描述一个用户接口、一个业务过程、一个数据库或信息流的特定语言。
Then you can generate code from those descriptions.
然后，你可以从这些描述中生成代码。
You can use Domain-Specific Language Tools to generate visual designers that are customized for your problem domain.
你可以为你的问题域，使用DSL语言工具生成自定义的可视化工具。
For example, you can create a tool to describe concepts that are specific to how your organization models business processes.
例如，你能够创建一个工具，用于描述你的组织如何处理模型化业务的概念。
If you are building a state chart tool, you can describe what a state is, what properties a state has, what kinds of states exist, how transitions between states are defined, and so on.
如果你正在创建一个状态图表工具，你能够描述以下被定义的信息：状态是什么、状态有什么属性、存在什么类型的状态、在状态间是怎样转变的，等等。
A state chart that describes the status of contracts in an insurance company is superficially similar to a state chart that describes user interaction among pages on a Web site.
在保险公司中，描述合约状态的状态图表与描述用户在Web站点间的交互页面的状态图很相似。
However, the underlying concepts between the two state charts will differ significantly.
然而，在两个状态图间的基本概念将有不同的值得关注的点。
By creating your own domain-specific language and custom-generated designer, you can specify exactly what state chart concepts you need in your tool.
通过创建你自己的DSL和自定义生成的设计器，你能够在你的工具中指定准确的、你需要的状态图概念。
