Application Development Framework
Background: What We Wanted – Business Drivers
• 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– JDeveloper - Visual editors, Property editors,
dialogs etc…
Overview
• Application Development Framework• Web, Desktop and Mobile applications• Meta-data Framework• Based on JEE Standard• Extendable• Follows MVC (Model View Controller)

Jdeveloper the IDE• Oracle’s tool for future development• Supports full development life cycle Design to
deployment• Wizard driven means less code to write less chances
of errors• One tool for all: Database, Desktop, Web, Mobile and
more• Provides cool features:
- Wizards- Change Control (Subversion, CVS)- Code templates- Code editors, Design view editors
• Drag and Drop
Why ADF
• Reduced complexity• Reusability• Usability• Promote service oriented development• Lesser Development and maintenance
cost• Standards-Based
