Chapter 1: Introduction to XML integration with DB2 for i5/OS - Pg. 3

1 Chapter 1. Introduction to XML integration with DB2 for i5/OS XML represents a fundamental change in computing. It allows applications to move away from proprietary file and data formats to a world of open data interchange. XML has become ubiquitous not only because of its range of applications, but also because of its ease of use. The text-based nature of XML makes creating tools easy. Also since it is an open, license-free, cross-platform standard, anyone can create, develop, and use tools for XML. In short, XML means portable data. In this IBM Redbook, we discuss all aspects of XML integration with DB2 for i5/OS. By presenting a simple retail store scenario, we discuss a broad range of technologies that can be employed to manipulate XML documents so that they can be stored in or retrieved from DB2. We also document end-to-end implementation methodologies that were hardened in production environments. Our goal is to make this redbook a reference publication for both traditional System i developers who use CL, RPG, and native APIs and those who prefer Java and graphical user interface (GUI)-based tooling. In this chapter, we introduce you to the related XML technologies, the advantages of DB2, XML to relational data mapping, and strategies for integrating XML with DB2 for i5/OS. © Copyright IBM Corp. 2006.
