data prefetching的意思|示意

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。

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。

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。

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。

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。

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。
