So at first in this paper, a disk - based xml data storage structure ldf & b based on f & b index is proposed. on one side, ldf & b wipes off the redundancy existing in traditional storage structure which stores the same value information repeatedly ; on the other hand, the index on the tape and the inverted index introduced in this storage structure enable nodes with the same property to be clustered when stored on disk, and enable nodes satisfied with the query to be searched effectively. that is to say, ldf & b can support xml query processing effectively
為此,本文首先提出了一種基於f & b索引的xml數據的磁盤壓縮存儲結構ldf & b ,其優點在於:一方面, ldf & b摒除了傳統存儲方法中相同的值信息重復存儲帶來大量冗餘的問題;另一方面,該結構引入的同帶索引與反向索引結構將具有相同性質的節點聚集在一起,使得可以快速的定位到滿足條件的節點集,很好的支持了其上的查詢處理。
