The emergence of XML is having an enormous impact on Web development, and scaling the learning curve of this new technology is a priority for many developers. The XML Bible offers a superb introduction to the subject and the groundwork to understand XML's future developments.
Author Elliotte Rusty Harold uses a patient, step-by-step discussion that clearly points out the potential of XML without boring his readership with tons of SGML spec-speak. Harold opens quickly with a "Hello World" example to get the reader coding early, and follows that with a simple but powerful example of XML's data management benefits--presenting baseball statistics. Once you've coded your first XML documents, you'll be hooked on the technology and motivated to learn about the more sophisticated topics.

Successful software developers have long recognized that proper modeling is a key element to the development process that leads to creating robust software. For the past decade, the Object Constraint Language has offered a more precise (but not very popular) means of expressing a software design -- more precise than even the Unified Modeling Language. The growing acceptance of the Model-Driven Architecture (MDA) approach, and the significant changes to the UML 2.0 standard have placed the OCL near the forefront of object-oriented application development. The OCL no longer represents a level of detail that practitioners are likely to ignore. The OCL is now closely tied to both the UML 2.0 and MDA standardization initiatives. This closeness is certain to lead to an increased level of popularity in this precision language for modeling. This book, from the creators of the language, explains how software professionals can use the OCL to create better
