Abstract

With storing XML data as a type of a column, relational databases have become more powerful. A relational database including both XML data and relational data is termed a hybrid XML-Relational database (XML-RDB) in this paper. Because existing keyword-search techniques on either relational databases (RDB) or XML databases (XML DB) cannot get appropriate results, we propose a new method of keyword search on XML-RDB to get more reasonable results than existing methods. To realize it, a new join operator, named XRjoin, is designed and utilized to join XML data with relational data. We construct a demo system by using DB2 v9.5, and our experiments show that the system can find the answers that we want to get.
