Third, this dissertation analyzes the complicacy of result size estimation problem for xml structure based query optimization compared to its counterpart in traditionally relational database, and proposes a full - featured result size estimation algorithm for xml query, sxm. for simple path expression query, this dissertation proposes a dynamic synopsis model for xml data based on the concept of f - stable and b - stable, xmap. for complicated path expression query, this dissertation adopts an improved bifocal sampling method for result size estimation
第三，分析了xml結構化查詢優化中的查詢代價估計問題與傳統關系型數據庫中的查詢代價估計問題的區別，提出了一套完整的xml結構化查詢代價估計體系sxm ，包括對簡單路徑表達進行查詢代價估計的動態xml數據統計模型xmap ，對復雜路徑表達進行查詢代價估計的雙焦點例舉法，以及對值匹配條件進行查詢代價估計的基於小波的多維直方圖方法，並能將多種查詢表達的查詢代價估計結果結合在一起，以給出一個完整的xpath查詢的代價估計。 -
