摘　　要：XML安全视图和查询重写是实现访问控制的关键技术。研究基于XML递归安全视图的查询重写问题,提出一种基于XPath查询语言、能处理递归视图的查询重写算法,避免了视图的物化和保存。该算法具有较高通用性,实验结果验证了其有效性。XML security view and query rewriting are the key techniques for access control This paper researches the query rewriting problem for XML recursive security view, and presents a query rewriting algorithm which based on XPath query and can handle recursive view. This algorithm avoids the view materialization and maintaining, and has high currency. Experimental results show that this algorithm is effective.
