图5演示了为一个自定义工作负载集群组指定连接属性和过滤标准。
Figure 5 shows where you specify the connection attributes and filter criteria for a custom workload cluster group.
这样一来，应用程序看到的就是一个统一的数据视图，而不必执行它自己的连接、过滤、排序等任务。
This lets an application get a consolidated data view of the data and therefore does not have to perform its own joins, filtering, sorting, and so on.
由于每个维度表过滤的选择度，每次连接都会减少事实表大小的十分之一。
Each join reduces the size of the fact table by one-tenth due to selectivity of the table filter on each dimension table.
