Through the implementing of kernel level file and cache mechanism at the client side, this newly proposed distributed network file system provides seamless network file access and reduces the performance decline caused by network transmission. utilizing the concept of logic block server, it provides the reliable data block storage and implements redundant storage capacity. utilizing the concept of the index server, it provide s the cost of the greatly for server and network during data access process and realizes the computing with balancing capacity
在客戶端通過實現內核級文件的調用和緩沖機制,實現了文件的無縫網路存取,並減少由於網路傳輸帶來的性能下降的影響;利用邏輯塊服務器實現邏輯塊的冗餘存取,實現數據塊的安全存放;利用索引服務器進行負載均衡計算,實現資料存取的較低網路和服務器開銷;利用索引服務器實現服務器組的零管理,使該系統具有高效性、穩定性和可伸縮性。This instructs db2 to pass the index keys to the sort program in memory, rather than having the keys written to and read once again from sort work files on dasd
這將指示db2將索引鍵傳遞給內存中的排序程序,而不是再次將這些鍵寫到dasd上的排序工作文件中,然後從中讀取這些鍵。To manage large - scale xml documents with complicated structure, this dissertation focus on the efficient structural indexing algorithm for xml data, result size estimation problem for xml structure based query optimization, result relevance ranking algorithm, and infrastructure for xml query processing for both text - rich and data - rich xml documents. to address the aforementioned issues, this dissertation makes the following contributions. first, it investigates the drawbacks of existing indexing algorithm for xml data, and propose a dynamic indexing algorithm for xml data based on d - bisimilarity, difx
為滿足結構復雜、大規模的xml數據管理需要,本文深入研究了xml信息檢索系統中的結構索引演算法設計和結構化查詢優化中的查詢代價估計問題,以及查詢結果和查詢條件間的相關度演算法,主要取得了4個方面的成果:第一,分析了已有的xml數據索引演算法中存在的問題,提出了一種高效的動態xml結構索引演算法difx ,它採用動態後向結構相似性( d - bisimilarity )的概念,可以根據實際查詢需求以及索引最優化的要求動態決定索引中保存的結構信息。
