- 12. The Challange • On one side: • JPA, EJB, Ajax, JavaScript, BPEL, SOAP, WSDL, RMI, JNDI, JDBC, O/R, HTML, DOM…. • On the other side: • Thousands of developers • Most don’t know these technologies • Most come from 4GL background • Expecting a visual and declarative approach • Don’t have time to learn all these new technologies • Need to focus on their specific application needs • How do you make it easy and approachable?
- 13. The Solution - Oracle ADF • Abstract developers from technology complexities • Example - UI Components abstracts from Ajax, Flash, Javascript, DOM • End-to-end framework • Implements best practices • Standards-based and extensible • Easy to develop with • Oracle JDeveloper provides visual and declarative experience
- 14. Oracle ADF An Enterprise Java Framework • Add value and simplify Java EE • Provides solutions for: • UI components and framework • Advanced Controller • Binding UI to business services • Declarative and proficient business services • O/R mapping • Visual and declarative development • Customization
