The focus of the federation pattern is to leave data in place and to provide a real-time, virtual, integrated view.
联合模式的重点是让数据保持在原来的位置，并提供实时的虚拟集成视图。
We described the data federation pattern as an approach to data operations against an integrated and transient (virtual) view where the real data is stored in multiple diverse sources.
我们在本文中对数据联合模式进行了说明，此模式是一种处理对集成临时(虚拟)视图的数据操作的方法，而此类视图中的实际数据都存储在多个不同源系统中。
To get the data in the right form, create a view - a new construct in MySQL V5 that assembles columns from other tables into a single, composite virtual table.
