In this case, the name of the page (Home.html) is automatically matched up with a class by the same name (Home.class).
在映射模型中，假如您想将一个UM l类映射为另外的名称，您需要改变其将要生成文件的名称，而不是类名。
If you map a UML class in the mapping model to a different name, you change the name of the file in which it will be generated but not the generated class in the file.
然后，工作负荷管理的管理员通过在工作负荷管理中创建定义来将事务类映射到服务类，其适用于分配请求的优先级。
The workload management administrator then maps transaction classes to service classes by creating definitions in workload management, which are used to assign the priority of the request.
即使您对部署CICSWeb服务不感兴趣，但您仍然可以利用从UM l类映射得到的db2表的COBOL代码。
Even if you are not interested in deploying CICS Web services, you still can take advantage of having COBOL code that USES a DB2 table that was mapped from the UML class.
这个服务用PHP编写，只拥有两个类：一个是执行函数的服务类，一个是TimeEntryui类映射到的php类。
The service is written in PHP and has only two classes: a service class that does the function and a PHP class to which the TimeEntry UI class is mapped.
名称属性在customer类映射到的表上定义外键，参考列定义Table CustomerOrder映射到的主键。
The name attribute defines the foreign key on the table to which the Customer class is mapped, and the referenced column defines the primary key to which the table CustomerOrder is mapped.
