这里的模型可以看作数据访问层，应用程序在这里与其他数据库和信息源交互。
The Model can be seen as the data-access layer, where the application interacts with any databases and information sources.
应用服务器的好处之一就是会自动在系统层间和应用程序间发送用户标识信息。
One of the great benefits of an application server is that user identity information is automatically sent between system layers and across applications.
DMS总是以同一种格式(数据图)返回信息，它隐藏了实际的数据存储信息，在SDO应用程序和EIS之间提供了一层数据提取的功能。
As a DMS always returns the information in the same format (a data Graph), it hides the actual data storage and provides a level of abstraction between the SDO application and the EIS.
该体系结构采用了具有抽象层的信息服务，这些抽象层可以最大化应用程序或企业流程与企业数据之间的松散耦合。
This architecture employs information services with abstraction layers that maximize the loose coupling between applications, or enterprise processes, and enterprise data.
用户交互层：用户交互层让用户可以与应用程序交互(例如，显示数据库中存储的信息)。
User interaction: the user interaction layer allows a user to interact with an application (for example, visualizing information stored in the database).
Web应用程序中关于用户访问的状态信息通过某种方式存储在服务器中，而不是客户机层。
State information about a user's visit within the Web application is stored somehow at the server, rather than the client level.
如果应用程序还使用层信息或Geohash信息，那么可以使用这些值来更好地缩小需要搜索的文档的范围。
If the application also USES tier information or Geohash information, then these values can be used for better narrowing down the number of documents to search.
最后，EAz为包装典型的交互详细信息提供一个方便的AuthorizationManager接口，并为应用程序的服务层提供一个更简单的接口。
Finally, EAz provides a convenient AuthorizationManager interface to wrap the details of the typical interaction and provide a simpler interface to the application's service layer.
这些合并文件包含Web应用程序层的一些配置信息。
These merge files contain some of the configuration information for the Web application layer.
