This well-established model continues to have strategic importance and is the basis for the continued growth of object/relational mapping and its associated persistence mechanisms. What is object/relational mapping (O/R mapping)? It's a programming technique that links a relational database to object-oriented language concepts. O/R mapping mechanisms allow a developer to create Java objects using an object-oriented perspective, eliminating the impedance mismatch that exists between object and relational models. O/R mapping is a compelling solution for you, as a Java developer, becau... (more)

The rise in prominence of Service Oriented Architectures (SOA) has triggered a storm of debates on how best to build enterprise SOA-based applications and establish a predominant industry position. In the meantime, the W3C XQuery language is accelerating toward "Recommendation" status; although comparatively little time has been spent debating XQuery-s role in SOA, I expect that its rising prominence will soon capture the attention of many Java developers seeking to build enterprise SOA-based applications. The W3C XQuery specification provides a native XML query language that in... (more)
