因此，大部分数据联合模式的实现对复杂转换功能的关注相对较少，而更强调查询优化技术。
Therefore, most implementations of the data federation pattern focus less on complex transformation capabilities and more on query optimization technologies.
我们此处描述的模式是使用uml模型实现的，可使用一些转换技术对这些模型进行优化。
The patterns we describe here are implemented using UML models, and have some transformation technology to refine those models.
数据联合模式的功能可以通过使用数据相关的技术(如优化器或补偿)或自己开发的应用程序来实现。
The functionality of the data federation pattern can be implemented using either database-related technologies such as optimizer or compensation, or by home-grown applications.
