分区数据集的一部分。
目标装载模块既不是分区数据集，也没有与源装载模块数据集相同的记录格式u。
The target load module is either not a partitioned dataset, or does not have the same record format, u, as the source load module dataset.
他们能够共同完成一个练习，其中包括使用大型机和传统的分区数据集(PDS)编译、执行和调试COBOL程序。
They were able to work together on the same exercise, which involved compiling, executing, and debugging a COBOL program using the mainframe and traditional partitioned data sets (PDS).
对于使用超大数据集工作的开发者来说，水平的分区和分片都是很重要的工具。
Horizontal partitioning is an important tool for developers working with extremely large datasets.
非分区表空间的单个数据集。
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。
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.
存储了整个数据集的子集的这些物理数据库被称为是分区、碎片或片。
These physical databases that store a subset of an entire dataset are referred to as partitions, shards, or slices.
由于数据集是按行进行分区的，可以对大型数据集（百万甚至十亿级的数据集）进行分布式训练。
The implementation partitions data by rows, allowing distributed training with millions or even billions of instances.
