指定对于有效的交换，哪些数据元素是必需的，哪些是可选的(基数)？
The specifications of data elements that are required and optional for a valid exchange (the cardinality)?
如果远程视图包含一个复杂的查询，那么使用表级统计信息(例如视图昵称的基数)可能使人产生误解。
If the remote view contains a complex query, using table-level statistics such as the cardinality for the nickname over the view can be misleading.
您可能已经注意到了，查询访问计划本身并未随着基数估计值的增大而改变。
You may have noticed that the query access plan itself did not change with the increase in cardinality estimate.
统计视图和REOPT都使优化器可以计算出更精确的基数估计，而后选择一个最佳查询执行计划。
Both statistical views and REOPT allow the optimizer to compute a more accurate cardinality estimate and consequently choose an optimal query execution plan.
因此，省略最大基数不会对已分配的内存量产生任何影响。
Therefore, omitting the maximum cardinality does not have any impact on the amount of allocated memory.
该表的基数为1,000,000，也就是说该表包含1,000,000行。
The table cardinality is 1,000,000, which means the table consists of 1,000,000 rows.
指定属性类型和基数：指定一个属性的几个特征，然后为所有属性重复该步骤。
Specify attribute types and cardinality: Specify several properties of one attribute, and then repeat that step for all attributes.
