A data partition, also referred to as a range (currently DB2 supports only a range partitioning scheme), contains a subset of rows that are stored separately from other sets of rows in the table.
数据分区也称为范围(当前DB 2只支持范围分区方案)，一个数据分区包含一个行子集，这些行存储在与表中其他行集不同的地方。
Each of the objects would correspond to a 'partition' and would allow each table space to contain a range of data which can be accessed very easily.
每个对象对应于一个“分区”，允许每个表空间包含一定范围的数据，这样非常容易访问。
RANGE/TABLE PARTITIONING (Available with DB2 9) - splitting data by key range over multiple physical objects within a logical database partition.
RANGE/TABLE PARTITIONING（DB29提供） ——根据键范围将数据划分到一个逻辑数据库分区中的多个物理对象上。
If database partitioning and range partitioning are used together, the rows in a table are first hashed across the database partitions and then range-partitioned within each database partition.
如果数据库分区和范围分区一同使用，那么表内的行首先会跨数据库分区做散列处理，然后再在每个数据库分区中执行范围分区。
Listing 3 creates a range-partitioned table with relational and XML data, rolls out (detaches) a partition containing old data, and rolls in (attaches) a partition containing recent data.
清单3创建一个包含关系和XML数据的范围分区表，滚出(分离)包含老数据的分区，滚入(附加)包含最近数据的分区。
