| 摘 要： | 为了提高XML电子病历系统查询和处理时间,采用倒排索引方法,引入LRU替换算法,并引进更新策略。该索引策略花费少量空间索引,但却适应了电子病历的实时更新,大大地提高了查询和处理时间。给出了此策略实现算法的同时,通过实验验证了它的有效性和优越性。

| Abstract: | To improve searching or processing speed from EPR(Electronic Medical Records) system based on XML,inverted index method was modified,which colligated the advantages of LRU replacement algorithm and updating strategy.It only spent little space index,however,it decreased the searching or processing time and adapted real-time data of EPR.Realizing algorithmic was given and the validity and advantage were validated experimentally. |
