因此，在使用标准的ODBC包装器的情况下，FederationServer只能将少数SQL操作下推到远程数据源，大多数谓词的计算、聚合、排序和连接仍然是在本地完成。
Thus, Federation Server can push down only a few SQL operations through the standard ODBC wrapper to the remote source and executes most predicate evaluations, aggregations, sorts and joins locally.
如果利用相同的分组关键字或者没有分组关键字，来聚合多个列，那么，所有的聚合都在单个数据传递中的相同操作中进行。
If more than one column is aggregated using the same grouping key or without a grouping key, then all the aggregations are computed within the same operation with a single pass over the data.

You should now have an understanding of the different forms of operation of this primitive and how it plays in aggregation scenarios.
对于聚合和组合，在数据库中对整体所做的操作通常需要同时对部分进行操作，而关联就不是这样。
With aggregation and composition, anything you do to the whole in the database you almost always need to do to the parts, whereas with association that is not the case.

SCA will be the design basis for creating components and application aggregates that can include interoperable components written in many different languages.
如果上下文比较简单，将通过一个跨页面连接执行；否则，将使用一个聚合组件和一个页面切换组件执行操作。
If the context is simple, this could be through a cross-page wire; if it is not, an aggregation component could be used with a page-switching component to perform this action.
