XML-Based Evaluation of Synthesized Queries

XML repositories are a common means for storing documents that are available through Web technologies. As the use of XML increases, there is a need to integrate XML repositories with other data sources to supply XML-oriented applications. In this paper, we examine documents that express business rules in XML format, and where the triggering and instantiation of rules requires execution of database queries. In this way, an inference process is governed by an XML document tree that controls the synthesis and evaluation of database queries.
