Enhanced usability of the user interface, a new technology for specifying component-level presentation, design patterns, and much more Web Models announces the brand new WebRatio 4.3, the model-driven development environment that integrates the visual modeling of Web applications and Web Services, the generation of code, and the automation of the documentation, evolution, and maintenance procedures. The new version delivers many novel features, among which a greater usability, thanks to a renovated user interface, and a revolutionary method for the specification of component-level presentation, for producing high-quality front ends with minimal effort and better integrating the work of the graphic designer and of the application developer. Specifically, WebRatio 4.3 offers: new powerful modeling primitives, like Master Pages, that is pseudo-pages whose content is specified once and inherited in all pages of the same module, and event-based operation chains, that is sequences of business rules activated upon access to a page or module a simpler, but at the same time more powerful, way of specifying component presentation.

It is possible to insert sets of pages and units in any project with a few clicks WebRatio 4.3 contains tens of other useful features, conceived in collaboration with developers for making Web application and Web Service development more effective. Download the release and try out the new features now! We will be happy to receive your feedback and make WebRatio more and more adherent to the requirements of complex Web application development.
