摘要
意大利人E.Damiani提出了一种XML访问控制模型(ED模型),但是该模型存在着要维护大量用户视图和查询时需重复解析等问题。通过引入数据库系统的支持,在数据库核心层实现采用ED模型的XML访问控制系统,可以有效地解决这些问题,并以实验验证了系统的效果和性能。
ED model is an effective model for XML access control.But it has some problems such as needing maintaining a large number of users＇ views and requiring parsing the XML document when handling every access request.The problems can be solved by implementing an XML access control system which adopts the ED model in the core of a DBMS.A way to design and implement the system is proposed,and the effect and performance of the system is verfied by experiments.
