Abstract:

This white paper discusses the role of an XML repository into today’s enterprise infrastructure. Virtually every database and repository provide some degree of XML support; however, there are important distinctions between support for XML as a data type and the role of a repository whose architecture and operations are optimized to support the broad family of XML recommendations and standards. Specifically, this white paper will explore: The nature and extent of XML use across the enterprise, cost and quality of service implications of an infrastructure with, and without, an XML repository, the evolution of XML repositories from both a technology and a market segment perspective, criteria to determine when an XML repository would add significant value to an existing infrastructure, and capability and packaging recommendations for XML repository functionality that can be used to evaluate specific offerings.
