In its simplest form, the preferred source, and thus the pattern, supports only find (read) operations.
在最简单的形式中，首选源及其对应的模式仅支持查找(读取)操作。
The pattern should support efficient updates of the preferred source, but this is somewhat problematic.
该模式应该支持对首选源的高效更新，但是这可能会带来问题。
Implementations of the data federation pattern vary in their capabilities which specific source models they can integrate.
数据联合模式的实现在其可以集成的具体源模型的能力方面各有不同。
One commonly occurring pattern involves the synchronization of data between corresponding sets of source and target integration endpoint systems.

For single source data, standardization of these default values may be through assigned mapping values, against a lookup table, or based on a defined pattern or algorithm within the data.
对于单个源数据，这些默认值的标准化可以通过根据一个查找表或定义好的模式或算法，在数据中指定映射值来完成。
A virtual catalog capability might leverage such a read-only pattern, as there's no need (or perhaps no ability) to update the preferred source.
虚拟目录功能可以利用这种只读的模式，因为它不需要(或者可能没有能力)更新首选信息源。
The mechanism (out of scope for this pattern) would run periodically to remove entity records that shouldn't be migrated from an alternate source to the preferred source.
这种机制（超出了这个模式范围）将周期性地运行，以删除那些不应该从备用源迁移到首选源的实体记录。

An implementation of this pattern may simply concatenate the individual source messages or may incorporate some more sophisticated set of data mapping capabilities.
此模式的实现可以直接连接各个源消息，或包含一些更为复杂的数据映射功能。
There are lots of systems that follow this pattern, where you write some modules / components in source code then describe how they are connected using an external config file.
许多系统都遵循这种模式，在这些系统中，你编写一些模块/组件，然后通过一个外部配置文件定义他们之间的连接。
One of the main reasons to apply this pattern is to leverage existing source systems with their data and capabilities.
应用此模式的一个主要原因是要利用现有源系统的数据和功能。
If an alternate source doesn't natively expose the same interface, you can apply a transform pattern to the source; however, this pattern is out of this article's scope.
