Provide extensive transformation capabilities in order to resolve conflicts between sources and in order to restructure source data into a desired target data mode.
提供各种转换功能，以处理不同数据源之间的冲突，并将源数据重建为所需的目标数据模式。
2
The order of the source data does not need to be maintained (BDD splits it into roughly equal buffers).
我们不需要维护源数据的顺序(BDD会把它们切分为大致相等的缓存)。

Basic transformations are used in many implementations in order to convert heterogeneous source formats into the common view at the federation layer.
