The complexity of web sites are increasing and transforming into web applications that contain business logic, interactivity, transaction handling and states. This phenomenon forces web developers to adapt more organized, simple and elegant techniques to keep the web applications error free, maintainable, reusable, well documented, etc. While this trend towards more useful interactive services, it also makes development of web applications much more complex. This Thesis focuses on developing a purely XML-Based web application framework that enables software developers and even non-programmers to build useful and highly interactive web applications quickly and easily using purely declarative language.
