ApproachesApproaches

Database developers Web developers

1. Develop a database schema.

2. In JDeveloper create an

application workspace.3. Create business services and

model layer using for exampleADF Business Components.

4. Implement view and controllerlayers using for example ADFFaces.

5. Test, debug and deploy theapplication.

1. Create an application workspace.

2. In the ADF Faces web-page

diagrammer, define your web pagesand page flow.

3. Create business services and themodel layer to support the view

layer.4. Generate database schema objects

based on the model layer.

5. Test, debug and deploy theapplication.

ADF FacesADF Faces

Implementation of the JSF specification

Standard look and feel UI components, suited fordatabase data representation, such as date pickers,advanced tables and colour

Client side validators and converters

Accessibility and multilingual support

Efficient implementation of client-side state saving,reducing per-component state saving size

Partial Page Rendering (PPR)Extended Faces tags

Different render kits to display on mobile phones,

PDAs, and telnet clientsIntegrates with the ADF Model Layer
