| Abstract: | XML (eXtensive Markup Language) security views is the key technique for access control. In this paper, the recursive DTD is studied, an algorithm that can avoid recursive views is presented and analyzed, and the algorithm can resolve the recursive view when the loop exist in DTD and improve the efficiency of query rewriting. |
