Abstract

By the use of the region coding and node model mapping method,an extended storage schema is presented for relational-database.We use breadth-first traverse XML tree to improve the structural join algorithms for processing parent/child relationships.The proposed method has advantages of saving memory,shrinking the scanning area of list and remarkably improving the rate matching of lookup.This algorithm improves the efficiency of XML data query.
