利用XML数据模型，可以将现有的XFDL表单与提供XML接口的应用程序轻松地集成起来。
XML data model makes it easier to integrate existing XFDL forms with applications that offer an XML interface.
XML数据模型可以将XFDL表单与提供XML接口的应用程序轻松地集成起来。
The XML data model makes XFDL forms integration with applications that offer an XML interface easier.
问题在于，遗留系统并不进行数据输入编辑和检验，因此不能确保应用程序中捕捉的数据与逻辑数据模型保持一致。
The problem was that the legacy systems did not have the data entry edits and validations to ensure that the data captured in the application was consistent with the logical data models.
由JAXB实现负责从数据模型类访问注释信息并在执行xml转换时应用这些注释。
It's up to the JAXB implementation to access the annotation information from the data model classes and apply these annotations when converting to and from XML.
Ganesh指出所谓规范的数据模型通常层次较高且对于实践应用来说过于抽象。
Ganesh points out that "the" canonical data model is typically too high-level and abstract for the practical use.
将XPath表达式从String转化为XPathExpression对象，然后将该对象应用于所支持的数据模型实例中的任何节点。
To convert an XPath expression from a String to an XPathExpression object, which can then be applied to any node in an instance of the supported data model.

WebDSL is domain-specific language for developing dynamic web applications with a rich data model.
关键是组件为应用程序的所有实例维护单一的数据模型。
The key is that the component maintains a single data model for all instances in an application.
EMF是用于基于结构化数据模型构建工具和其他应用程序的建模框架和代码生成工具。
EMF is a modeling framework and code generation facility for building tools and other applications based on a structured data model.
另外，您可以在物理数据模型中获取这个列应用的隐私策略的有关细节，并轻松导航到关联的物理数据模型本身。
In addition, you can get details about the privacy policies applied for this column in the physical data model and easily navigate to the associated physical data model itself.
它们从数据库捕获核心数据模型以及应用于这些数据的业务规则。
They capture the core data model from the database and also the business rules that apply to this data.
就像uml模型是应用程序架构的抽象一样，数据模型表示信息模型的抽象。
Like UML models that are abstractions of the application architecture, data models represent the abstraction of the information model.
通过内置的模型间转换和清晰的业务需求连接，跨流程、服务、应用程序和数据模型实现架构一致性。
Achieve architectural alignment across process, service, application and data models with built-in transformation between models and clear linkage to business requirements.
SDO还提供了一个元数据api，允许应用程序、工具和框架对数据图形的数据模型进行自检。
SDO also provides a metadata API, which allows applications, tools, and frameworks to introspect the data model for a data graph.
可以将可扩展性机制加入到UI、服务组件接口、服务组件本身以及数据模型中，从而实现可配置应用程序。
Configurable applications can be achieved by working in extensibility mechanisms into the UI, the interfaces of the service components, the service components themselves and the data models.
您将一个应用程序模型转换为逻辑数据模型，并最终创建了数据库数据表。
You transformed an application model to a logical data model for finally creating the database tables.
前面已经提到，解析器回调应用程序以建立数据模型，解析器处于控制地位。
The parser issues callbacks to the application to build the data model, as discussed before, but the parser is in control.
只不过这种方法不根据xml语法定义通用的数据模型，其解析器依赖应用程序程序员建立定制的数据模型。
Rather than define a generic data model based on the XML syntax, the parser relies on the application programmer to build a tailor-made data model.
此外，执行恢复请求后，将不会更新应用程序的数据模型并且也不会调用操作方法。
In addition, the application's data model won't be updated and no action method will be called after a restore request.
相反，可以选择使用规范中定义的标准SDOAPI来创建数据模型的实例，以将数据传输到其他应用程序。
Instead, you have the option of using the standard SDO APIs defined in the specification to create instances of the data model to transfer data to other applications.
您已经妥善设置了与您的数据模型相匹配的CMR，即使应用程序代码并没有显式的使用它们。
You have everything to gain and nothing to lose to set up the appropriate CMRs that match your data model, even if the application code does not explicitly use them.
注意，针对以上数据模型执行相同的应用程序花费了16秒(在数据被重组以后)。
Note that executing the same application against the above data model took 16 seconds to execute (after the data had been reorganized).
但是，虽然这个应用程序缺少正式数据模型，但也许我们可以将数据存储到内存中的数据库，并凭借该数据库进行查询，通过这种方式借用一个数据模型。
But, while this application had no formal data model, maybe we could "borrow one" by streaming the data into an in-memory database and querying against that.
