Storing AXML documents with ARAXA

Abstract. Active XML (AXML) documents combine extensional XML data with intentional data defined through Web service calls. The dynamic properties of these documents pose challenges to both storage and data materialization techniques. We present ARAXA, a non-intrusive approach to store AXML documents. It takes advantage of complex objects from object-relational DBMS to represent both extensional and intentional data. By using a DBMS we benefit from efficient storage tools and query engine. We have defined a storage mechanism with a methodology to materialize AXML documents at query time. We have also implemented a prototype of ARAXA. Our experimental results show that our approach is scalable and extensible. 1
