- You can apply multiple aggregations.
可以应用多个聚合。 - A pattern of overlapping aggregations is usually found.

可在整个列上计算聚合，或者由作为函数的第二个参数所给出的分组列指定的子组上计算聚合。 - But, if you need to perform data analysis queries with grouping and aggregations, you may prefer SQL/ XML.
但若您需要执行带有分组和聚集的数据分析查询，那么SQL/XML是更好的选择。 - Start by generating the query using the first aggregation function ( SUM in the example) in the measure's list of aggregations to aggregate the template expression.
先使用度量的聚合列表中的第一个聚合函数（在这个示例中是SUM）对表达式模板进行聚合，产生一个查询。 - Aggregations and compositions are treated the same way in NIEM.
聚合和复合在NIEM中受到同等对待。 - In the add aggregations from query log window, assign a name to aggregation design name and aggregation prefix.

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。 - But if you use multiple aggregations with the same grouping keys, or multiple counting functions that count the same column, it will not significantly increase the execution time of the rule.
但是，如果使用具有相同分组关键字的多个聚合，或者对相同列进行计数的计数函数，其不会显著增加规则的执行时间。
