Using multi-dimensional clustering for query performance.

使用多维聚簇提高查询性能。

youdao

As in previous releases, administrators use the ORGANIZE BY dimension (...) clause of the CREATE TABLE statement to specify multi-dimensional clustering.

与以前的版本一样，管理员使用CREATE table语句的ORGANIZE BY DIMENSION(…)子句指定多维聚簇。

youdao

To support such a query, an administrator can use multi-dimensional clustering to instruct DB2 to physically organize rows in the SALES table by these dimensions.

为了支持这样的查询，管理员可以通过使用多维聚簇让DB 2按这些维组织sales表中的行。
