PREFETCHSIZE specifies the number of pages to be read from the table space when data prefetching is being performed.
PREFETCHSIZE指定在执行数据预取时将从表空间读取的页数。
Feedback directed data prefetching optimization has become one of the advanced compiler optimization techniques. it can do well in linked data prefetching.
反馈式数据预取优化技术是当前高性能计算技术中前沿的一种编译优化手段，可以很好地解决链式结构的预取问题。
Because of the number of table scans and table sorts in the TPC-H workload, prefetching data from disks into memory is important for optimal performance.
因为TPC - H工作负载中表扫描和表排序的数量较多，所以为获得最佳性能将数据从磁盘预取到内存是很重要的。
With this approach, however, we still advice against general prefetching if it is not known what prefetched data is actually needed in subsequent requests.
不过，使用此方法时，如果知道在后续请求中将要实际需要哪些预提取数据，我们仍然建议使用普通的预提取功能。
Hence, the system needs to fetch the needed data as soon as possible. The existing way is based on file prefetching.
因此若要降低使用者等待时间，则需加快反应时间，必须尽早取得档案资料。
In this paper, this algorithm was based on the data update rate and it increased the size of the selected data to determine and sort, then made the choice of the prefetching data.
在此算法的基础上增加对数据更新率及大小的判断并对所选数据排序，然后进行预取数据的选择。
The corresponding prefetching algorithm, which comes from the sequential pattern mining method in data mining area, is also raised.
借助数据挖掘领域中序列模式挖掘的方法，提出了相应的预取算法。
Data hoarding technology means the technology of prefetching data which may access by user after disconnection later to cache.
数据收集技术是指在断接前把用户将来可能访问的数据预先存储到本地缓存的一种技术。
Data Hoarding is a key issue in mobile database. It will support the autonomy operation of mobile hosts when they are disconnected from servers by prefetching important data into local cache.
数据收集是移动数据库中的一个关键问题，将数据收集到移动客户机的缓存中，使客户机在断接期间使用本地数据自主操作，提高了数据的可用性。
