数据被划分到一个数据库分区组中的所有分区上，可以为数据库分区组添加一个或多个数据库分区，或者从中去掉数据库分区。

Data is divided across all the partitions in a database partition group and you can add or drop one or more database partitions from a database partition group.

youdao

为此，可以将用户表放在不包括IBMCATGROUP数据库分区组中的数据库分区的数据库分区组中。

This is accomplished by placing user tables in database partition groups that do not include the database partition in the IBMCATGROUP database partition group.

用户可以通过使用数据库分区组和表空间，来确定将表数据分布到哪些数据库分区上。

Using database partition groups and tablespaces, a user can determine across which and how many database partitions their table data is to be spread.
