1. Application Development
Framework

2. Background: What We
Wanted – Business Drivers
•Cutting Edge UI
•Agility
•System Integration
•Standards
•Scalability, Security, Portability
•Time to market

3. 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?

4. 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…

5. Overview
•Application Development Framework
•Web, Desktop and Mobile applications
• Meta-data Framework
• Based on JEE Standard
• Extendable
• Follows MVC (Model View Controller)
architecture

8. Languages need to know
Language Level of
knowledge
Usage
Java Intermediate For Custom logic coding
JavaScript Basic/None For User interaction
functionality
XML Basic Syntax
familiarity
JSF is XML style language
HTML Basic/None JDeveloper generates
automatically but useful to
know
Groovy Basic For Validation checks and
attribute expressions
CSS Basic/None To Skin the application
Expression
Language
Basic Supply data to components
from properties or
Method

9. 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

10. Why ADF
•Reduced complexity
•Reusability
•Usability
•Promote service oriented development
•Lesser Development and maintenance
cost
•Standards-Based

11. Features of ADF
