Lessons Learned from DB2 pureXML Applications: A Practitioner's Perspective

摘要

Beyond using XML as a message format, more and more companies are storing XML data permanently in a database. Database researchers and vendors alike have spent a lot of effort on designing, studying, and implementing XML database technology. In this paper we report our experiences from working with a broad variety of companies that have developed and deployed XML applications on top of DB2. We discuss three real-world XML database scenarios and their design considerations, and describe recurring patterns in XML applications. We highlight common concepts and observations, and document challenges that point to future work for the database community.
