If the partitioning key for a table to be loaded in the database is an integer that has possible values between 1 and 500,000, the partitioning key is hashed to a partition number between 0 and 4 095.
如果数据库中所装载的表的分区键是1到500,000之间的整数，则分区键被散列到0到4 095之间的一个分区号。
A typical design for a database with monthly roll-out based on sale_date, would be to use sale_date as the table partitioning key and create a separate partition for each month.
对于需要每月根据sale_date转出数据的数据库，一种典型的设计是使用sale_date作为表分区键，并为每个月创建一个单独的分区。

Enter the number of the partition you want to connect to, and press the Enter key.
输入您想要连接到的分区编号，并按enter键。
RANGE/TABLE PARTITIONING (Available with DB2 9) - splitting data by key range over multiple physical objects within a logical database partition.
RANGE/TABLEPARTITIONING（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。
A partitioned key is a column, or group of columns, used to determine the partition in which the particular row of data is stored.
分区键(partitioned key)是指一列或一组列，用于确定特定行数据所存储的分区。
If no columns satisfy the requirement for a default partitioning key, the table is created without one, which means the table cannot span more than one partition.
如果没有列能满足作为默认分区键的条件，则表在创建后就没有分区键，也就意味着这个表不能横跨一个以上的分区。
If collocation is not a major consideration, a good partitioning key for a table is one that spreads the data evenly across all database partitions in the database partition group.
如果不需要特别考虑并置，那么能使数据均匀地散布在数据库分区组中所有数据库分区上的分区键就是好的分区键。
If an object will be looked up by two or more keys, the most reasonable key that you partition by would be the most commonly used key.
如果根据两个或多个键查询一个对象，进行分区所依据的最合理的键将是最常用的键。
In a DPF environment, each table row is distributed to a database partition according to the distribution key specified in the CREATE table statement.
在DPF环境中，根据CREATE table语句中指定的分区键，表中的每个行被分布到一个分区上。
Distributing both tables by hashing on their join key (pdb_id) also ensures that all atom rows for a given PDBML document are stored in the same database partition as the PDBML document itself.
通过对上述两个表的连接键(pdb_id)进行散列处理来分布两个表也能确保给定pdbml文档中所有原子行均能作为本身的PDBML文档存储在相同的数据库分区中。
