Introduction to Oracle ADF

What is Oracle ADF?

• In Computing, Oracle Application Development Framework, usually called Oracle ADF
• It is an end-to-end development framework, built on top of the enterprise java platform, providing out-of-the-box infrastructure services and a visual declarative development experience offering unparallel productivity to application developers.
• The framework provides integrated infrastructure solutions for the various layers of the application & easy to develop on the top of them.

Features of Oracle ADF :-

• Powerful components for REA(Rich Enterprise Application)
• It includes a set of over 150 standard based JSF
• These components offer data interaction, data visualization & encapsulated browser side operations.
• Page Flow 2.0
• Oracle ADF extends basic JSF controller to provide the ADF controller.
• ADF controller helps to enhance page & flow control, comprehensive state management & re usability of flows.
• Drag & Drop data binding
• ADF provides a data binding framework that simplifies the task binding UI to business service down to drag & drop operations in and IDE.
• ADF Business Components
• ADF is concerned the main data source which is also called as the data model in generic terms is based on ADF BC.
• Prime components of BC are:- EO(Entity Object), VO(View Object), Association & View Links, AM(Application Module) & BC Tester(Business Component Tester).
• IN ADF 11g BC tester is used to run & test model layer without creating UI. BC Tester internally uses an applet to run.
• Security
• ADF Security is based on OPSS(Oracle Platform Security Services) OPSS is security foundation for oracle fusion middleware.
• Existing investments can be reused, like Oracle Access Manager for single sign on(SSO), OID & Mircosoft active directory for LDAP services.
• Declarative Application customization
• An ADF application can be customized without modifying the base data source.
• Customization can be done for each of the layers of the framework achieving customized application fitting the need of specific users.
• Productivity
• Jdeveloper provides the ability for the developers to choose directly manipulate source code at anytime.
• Jdeveloper provides complete debugging solution allowing to set breakpoints within multiple language.
• Along with superior reusability, it supports reusability through ADF libraries & ADF Business resource catalogue.
 

Advantages of using ADF :-

• Supports Rapid Application Development. 
• Based on MVC Architecture.
• Declarative Approach (XML Driven)
• Secure
• Reduce Maintenance Cost
• SOA enabled. 

Various Components in ADF :-

• ADF Business Components(Model).
• ADF Faces(View)
• ADF Task Flows(Controller)
