DRXQP: A Dynamic Relational XML Query Processor
B. M. Monjurul Alom, Frans Alexander Henskens, Michael Richard Hannaford · 2010
The most promising and dominant data format for data processing and representation on the Internet is the semistructured data form termed XML. XML data has no fixed schema; it evolved and is self describing which results in management difficulties compared to, for example, relational data. It is therefore a major challenge for the database community to design query languages and storage methods that can retrieve semistructured data efficiently. In this paper, we present a querying scheme for semistructured data views of relational form. The proposed technique stores element-paths, attributes, contents of the element paths and attributes, and XML processing instructions in a dynamic relational structure termed as Multi-XML-Data-Structure (MXDS). We also analyse relational query processing time and XML query processing time to compare the query performance. The presented technique supports different types of XML query.
