手持设备中股票软件数据存储方案的设计

Design for Data Storage Scheme in Stock Software of Handle Device

针对股票软件中历史数据的特点,深入分析了B+树存储和线性表存储两种数据存储方案。这两种方案均能达到股票软件的应用要求,最后进一步从性能和资源耗费上对这两种方案进行了对比分析,指出了它们各自的优点与不足,对其他类似的设计具有很好的借鉴意义。

Specially for the history data of stock software,two storage schemes which are B+ tree storage scheme and linear table storage scheme are analyzed in this paper.Both of them can satisfy the application demands of stock software.At last,their performances and logic resource are also compared,and thus their advantage are disadvantage and pointed out respectively.Therefore,this design can offer certain reference sense to similar designs.
