Forms and Designer Users:What are your Expectations?

� Development Productivity

– Modeling

– Visual and declarative development

� Runtime Efficiency

– Performance and scalability

– No need to code the “plumbing” infrastructure

� Different architectures– J2EE Best Practices

– Service Oriented Architecture

– Event-Driven Architecture

� Different technologies– WS, BPM, XML, WSDL, Portal, Wireless, etc.

� Different data sources & access– Database, Legacy, Packaged Apps, WS, etc.

� Diverse set of developers– Different technical skills

– Different development styles

– All need to be productive

Development Challenges Now

4

Next Generation of J2EE Tools

� Reach a Broader Audience

– Bring the power of J2EE to corporate developers

� Increase Productivity and Ease of Use

– Visual and declarative development

– Less coding, more reuse

– Bridge the usability gap with C/S tools

� Reduce Learning Curve / Staffing Issues

– Provide abstraction on top of J2EE

Oracle ADF

� Simplifies J2EE Development

– Visual and declarative set of tools

– Rapidly becoming as productive as Forms

� Implements Best Practices

ADF Model

Business Services


Model

Controller

ADF Model

� Abstract service implementationfrom clients

– EJB, Web Services, Toplink, Java Classes, etc.

– Service Oriented Interface

� Declarative Data Binding

– Common binding of data to UI components

– Uses EL (standard expression language) to reduce learning curve

– Clean separate of view and model

� Declarative Data Validation

– Consistent interface for common validation

– Extendable for complex application validation

� Design Tools
