摘要 数据存储是有效提高系统性能的方法之一.由于受带宽和无线传输速度的限制,将频繁出现的数据存储在移动数据库系统中显得尤为重要.本文实现了一个数据存储的算法(HighFrequent Data Caching),并通过模拟的方法实现了HFDC与经典的LRU(Least Recently Used)两个算法在性能上的比较. Data storage is one of the effective ways in improving system performance. Because of constraints about speed of broadband and wireless transmission, Storing data that appear high frequently in the mobile database system is to be particularly important. In this paper, we have achieved a data storage algorithm： HFDC （High Frequent Data Caching）, and through simulationed approach to the HFDC with the LRU （Least Recently Used） in the two algorithm performance comparison.
