双语例句
- If a rule must contain one aggregation, then you can compute additional aggregations on different columns in the same rule without impacting performance, as long as the grouping keys are the same.
如果规则必须包含一个聚合，那么可以在同一规则中，对不同列计算附加聚合，只要分组关键字相同，就不会影响性能。 - A measure must have one aggregation with an empty list of dimensions, and any other aggregations must each have an explicit list of dimensions.
一个度量必须有一个维列表为空的聚合，其他聚合必须都具有明确的维列表。 - Composite applications are aggregations of user interface ( UI) components that are loosely coupled to support intercomponent communication.
复合应用程序由松散耦合的用户界面（UI）组件组成，支持组件之间的通信。 - The query model defines the concepts of dimension selections, edges, cube views, and the aggregations and manipulations of dimensional data.
查询模型定义维度选择、边界、立方体视图以及维度数据的聚合与操纵等概念。 - 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。 - You can compute aggregations on the whole column, or on subgroups that are specified by the grouping column given as the second parameter of the function.
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 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。 - Composite applications are aggregations of user interface components that are loosely coupled to support inter-component communication.
复合应用程序由一些用户界面组件集合而成，这些组件通过彼此松散耦合支持组件间通信。 - Almost any data consolidation scenario with tasks ( such as joins, merges, filtering, and aggregations) that can reduce input data early in the data flow can benefit from T-ETL processing.
凡是具有能在数据流早期减少输入数据的作业（例如连接、合并、过滤和聚合）的数据整合场景，几乎都能从T-ETL处理中受益。 - 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.
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。
