Develop Applications with Oracle ADF 1 - * Oracle Application Development Framework (ADF) Oracle ADF is an end-to-end application framework that builds on Java EE standards and open-source technologies to simplify and accelerate implementing service-oriented applications. It is fully extensible and customizable by adding or modifying libraries. ADF simplifies the tasks of: Creating business services Designing user interfaces to access those services. Oracle ADF simplifies Java EE development by minimizing the need to write code that implements design patterns and the application infrastructure. These implementations are provided as part of the framework. Oracle ADF also provides a visual and declarative development experience that minimizes the need to write code and reduces the learning curve for 4GL developers. Business services are implemented as metadata, enabling them to be bound to user interfaces in the same manner regardless of the technology employed in the underlying data model. The use of metadata also enables business rules for data-bound fields to be specified at the model layer, along with labels, validation, and tooltip properties. Instructor Note: The use of metadata in wiring UIs to services is probably the most important point to emphasize. * Enterprise developers need more capabilities to create complete application in a more declarative way. While Java EE is a step in the right direction there are still pieces missing to provide true productivity and reusability. Develop Applications with Oracle ADF 1 - * Here is what each of the components of ADF provides * We are now creating these type of Uis – actual screenshots from our Fusion applications * The ADF Controller ADF Controller is an enhanced navigation and state management model on top of JavaServer Faces. Whereas the JSF page flow comprises just pages and navigation rules, the ADF Controller offers much more functionality. It enables you to describe page flows declaratively. Page flows ca
