Abstract

Very few research works have been done on XML access control over relational databases despite the fact that there is an undeniable amount of XML data stored in RDBMS. Moreover, the proposed algorithms in the literature have performance drawbacks. In this paper, we propose an efficient and well-defined XML access control model for schema-based relational storage of XML documents which overcomes the shortcomings of existing work. We also present the challenges of translating XML access control rules to relational access control rules and define an efficient and sound algorithm for this task.
