| Abstract: | In this paper,we analysis the advantages and disadvantages of XISS,DBXI and indexes based on DDT and propose an XML indexes based on XML schema to improve the efficiency of XML query.Our indexes can support searching many XML documents based on different XML schema.It take into account the validation of the XML document and determine the invalid query.We reserve some space when encoding.By this way,it is easy to updata the document.Our indexes can effectively support structure connection computing and path ... |
