  3. Main characteristics of dbxi are : 1 ) a new xml numbering scheme is adopted which enables each element in xml documents carries corresponding dtd structural information. 2 ) a path query with n elements ( or attributes ) and a predicate restriction can be implemented with only 0 or 2 structural join operations per xml document while at least n - 1 times of structural join operations are needed in xiss ( xiss is a kin xml indexing system developed by q. li and b. moon ). 3 ) for a path expression that is not complying with any paths in xml documents, dbxi can give a judgment of no answer in much shorter time than that of sphinx, xiss, etc. experimental results demonstrate that dbxi can process path expressions much faster than lore sphinx and xiss do

    Dbxi的主要特點是: 1 )採用了新的xml編碼方法,使xml文檔中每個元素屬性的編碼攜帶了相應的dtd結構信息; 2 )對一個由n個元素屬性組成的有一個謂詞約束的路徑表達式, dbxi處理每個xml文檔,由同類系統xiss所需的至少n - 1次結構連接,降低至0次2次結構連接; 3 )如果查詢路徑在待查xml文檔中不存在正確的匹配結構, dbxi能夠在比國際上的sphinx和xiss等xml方法較短的時間內給出無查詢結果的判斷。
