如果有，那么它们仍然生成一个压缩字典，但是在这里，没有被压缩的记录，因为所有数据已经被移到表中。
If so, they still generate a compression dictionary, but in this case, there is no compressed record, as all data has already been moved into the table.

构建好字典之后，任何新传入的数据都要进行压缩。
Once the dictionary is built, then any new incoming data is subject to row compression.

The table dictionary is built only when a REORG is performed, after which the data in the table can be compressed.
顾名思义，是自动创建压缩字典的处理过程。
ADC, as named, is the processing whereby a compression dictionary is automatically created.
对于非常小的表，压缩字典的大小(8KB到64 KB)有可能会抵消掉通过压缩所节省出来的空间。
For very small tables, the size of the compression dictionary (8 KB to 64 KB) may offset any space savings that compression provides.
在DB 2 9.5中，添加了自动字典创建，所以不再需要自行构建字典；在DB 2 9.7中，索引和临时表现在可以压缩。
In DB2 9.5, automatic dictionary creation was added so you no longer had to deal with building a dictionary yourself; in DB2 9.7, indexes and temporary tables can now be compressed.
DB 2 Viper 2中引入了自动字典创建特性，以进一步增强行压缩。
In DB2 9.5, the automatic dictionary creation feature is introduced to further enhance the row compression offering.
在DB 29中，REORGTABLE命令中的默认压缩字典指令是KEEPDICTIONARY。
In DB2 9, the default compression dictionary directive for the REORG TABLE command is KEEPDICTIONARY.
对于其他接口，如图1所示，抽样数据(用于构建adc字典)直到执行离线table reorg时才被压缩。
For other interfaces, the sampling data (used for building the ADC dictionary) remains uncompressed, as seen in Figure 1, until an offline table reorg is performed.
Burrows - Wheeler通过对未压缩的源文件中的相关字符串进行分组来操作，而不是象Lempel -Ziv风格那样构建一个字符串重现的字典。
Burrows-Wheeler operates by grouping related strings in a uncompressed source, rather than in the Lempel-Ziv style of building up a dictionary of string occurrences.
本教程通过一系列的练习让您熟悉这项新的基于字典的行压缩特性。
This tutorial takes you through a series of exercises to familiarize you with this new dictionary-based row compression feature.
在DB 2 9.1中，只有在建立了表字典之后(表字典通常是在表reorg阶段建立的)，压缩才能生效。
In DB2 9.1, the compression takes effect only after the table dictionary is built, which is usually during the table REORG phase.
深度压缩知识一个例子(IBM在DB 29中引入了深度压缩)，但要使用它，您必须了解如何启用它和如何构建压缩字典。
Deep compression is just one example-ibm introduced deep compression in DB2 9, but in order to use it you had to know how to enable it and how to build a compression dictionary.
