      • Cutting Edge UI
      • Agility
      • System Integration
      • Standards
      • Scalability, Security, Portability
      • Time to market
    • Problem: The Development Challenge
      • 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?
    • The Solution - Oracle ADF Framework
      • Development framework that simplifies development of Java EE-based SOA applications
      • Abstract developers from technology complexities
        • Example - UI Components abstract from Ajax, Flash, JavaScript, DOM
      • Provides end-to-end infrastructure solutions
        • O/R Mapping, persistence, caching, controller, binding, UI framework, security
      • … and an easy way to use them
