在此上下文中，资产不是上面所定义的现有资产，而是任意抽象级别的任何类型的软件开发资产，包括设计模型、模式和代码实现。
In this context, an asset is not an existing asset as defined above, but any type of software development asset at any level of abstraction, including design models, patterns, and code implementation.
在特有的情境下，开发人员可能会利用转换来更新或创建一组带有抽象模型中所包含的新的信息的模型或代码。
In a typical scenario, a developer would use a transformation to update or create a set of models or code with new information in the abstract model.
还可以根据需要相对较快地改变技术，因为重要的设计信息是一个抽象模型，没有嵌入到代码中。
And you can change technologies reasonably quickly as needed because the important design information is in an abstract model, not embedded in the code.
引起问题的另一个原因就是那些模型经常首先使用类元素(例如：联合和抽象)，在代码中它们仅仅是通过名称被引用。
Another cause of problems is that models often use first class elements (for example, associations and abstractions) for what in code would be just simple references by name.
通过设计特殊的设计模式，开发人员可以更灵活地控制所生成的代码，这就不简单地拘泥于抽象模型了。
By designing around a particular design pattern, developers have greater flexibility to control the generated code, which is not constrained simply based on an abstract model.
自动操作：框架结构的潜在模型，以及映射允许模型的半自动转换，从高层级到低层级的抽象，并最终转换为可执行代码。
Automation: the framework's underlying meta-model and mappings allow for the semi-automatic transformation of models, from higher to lower levels of abstractions, and eventually to executable code.
在两部分组成的关于XSLT的系列文章的第一期中，介绍了XSLT 2.0的一些新特性，并说明了如何从抽象数据模型生成代码。
In the first article of this two-part series on XSLT, I introduced you to some of the new features in XSLT 2.0 and showed you how to generate code from an abstract data model.
在结束项目时，您将拥有系统的抽象模型、构建数据库的SQL代码和用于每个表的PHP包装器。
By the end of this project, you'll have an abstract model of your system, SQL code to build the database, and PHP wrappers for each table.
首先将抽象模型转化成数据库物理模式模型，然后使用该模式模型构建SQL代码。
The first transformation turned the abstract model into a database physical schema model. I then used this schema model to build the SQL code.
这个模型元素vehicle的代码显示在列表9中。尽管这些接口的定义与那些类定义十分相似，但是这些接口下面的操作通常是抽象的。
The code for the model element Vehicle is shown in Listing 9. Although the definitions for these interfaces are similar to those of classes, the operations under these interfaces are always abstract.
SOA设计与开发平台应该允许进行模型的半自动化转换，从而从高抽象级别转换到低抽象级别，最终转换为代码。
An SOA design and development platform should allow for the semi-automatic transformation of models from higher to lower levels of abstraction, and eventually to code.
使用MDD可在质量和效率上都有所提高，因为较低级别的抽象是从较高抽象级别的模型得到的，而低级别的抽象最终将用于生成代码。
Using MDD allows for quality and productivity gains because models at lower levels of abstractions are generated from models at higher levels of abstraction, which eventually lead to code generation.
在程序语言中，语法包含了一个抽象的模型，所有格式良好的代码单元(即源文件)都必须匹配这个模型。
With a programming language, the grammar contains an abstract model that all well-formed units of code (that is, source files) must match.
位于抽象模型和代码模板之间的中间模型使用XML模式，生成PHP 和SQL 的代码模板则使用文本模式。
XML mode is used for the temporary models that sit between the abstract model and the code templates. Text mode is used in the code templates when you generate the PHP and the SQL.
本文叙述了并行程序设计语言occam的编译结构、抽象微码模型机、代码生成以及它的设计原则。
The paper describes the compiler structure, abstract microcode machine, code generation of OCCAM and its designing principles.
之后介绍了源代码向抽象数据模型的转化过程，重点阐述了代码抽取模式和系统源代码分析过程；
Then introduced the transformation process that from the source code to the abstract data model. Focus on the code extraction patterns and the analysis of the system source code process.
