事件表存储数据库触发器在分段表中生成的异步事件。
An event table stores the asynchronous events generated by the database triggers in a staging table.
分段表空间:分段表空间可以包含一个以上的db2表。
Segmented: a segmented table space may contain more than one DB2 table.
分段表(在多分区数据库环境中装载实用程序不支持这种表)。
Staging tables (not supported by the load utility in multiple partition database environments).
下面列出了分段表空间相对于简单表空间的一些性能优势。
Listed below are some of the performance advantages of segmented table Spaces over simple table Spaces.
分段的最终目标就是通过直接访问来包含满足SQL查询的数据分段表,减少检索时间。
The ultimate goal of fragmentation is to reduce the retrieval time by directly accessing the fragment that contains the data that satisfies the SQL query.
在单个dbspace中可以存储同一个表或索引的多个片段,从而减少分段表所需要的dbspace总体数量。
You can store multiple fragments of the same table or index in a single dbspace, reducing the total number of dbspaces needed for a fragmented table.
与在单个dbspace中保存多个表或索引片段提高了查询性能,这样做胜过将每个分段表达式存储在不同的dbspace中。
Storing multiple table or index fragments in a single dbspace improves query performance over storing each fragmented expression in a different dbspace.
使用分段的或分区的表空间。
分段和PD Q优先级也对于数据的检索速度有极大的影响,并有助于表扫描。
Fragmentation and PDQ priority also have a huge effect on the speed of data retrieval and will help table scans.
例如,按照事务日期列分段的销售表,每个月都将添加新的行来存储当月的销售数据。
For example, a sales table fragmented by transaction date column such that new rows are added each month to store current month sales data.
将非分段的表从一个dbspace移动到另一个dbspace。
Moving a non-fragmented table from one dbspace to another dbspace.
表按照表达式、LIST或INTERVAL策略分段。
Table is fragmented by expression, LIST, or INTERVAL strategy.
