• Developer Tools choice• Oracle ADF overview

Rich Internet Web Applications

What We Wanted – Business Drivers

C tti Ed UI• Cutting Edge UI• Refresh data on page without full page refresh• Immediate validationImmediate validation• Drag-and-Drop• Pop-up

D i d l l t• Dynamic and complex layouts

• Agility• System Integration• System Integration• Standards

Scalability Security Portability• Scalability, Security, Portability• Time to market

How We’ll Get There

Oracle Fusion – What Is It?

O l F i A li ti• Oracle Fusion Applications • Oracle’s next generation of enterprise applications

• Oracle Fusion Middleware• Oracle Fusion Middleware• Integrated standards-based middleware platform

• Oracle Fusion Architecture• Oracle Fusion Architecture • Recommended architecture for your custom applications

What is the Fusion Product Stack?

O l JD l th d l t t l• Oracle JDeveloper – the development tool• Oracle ADF – the development framework

O l SOA S it th i t ti l• Oracle SOA Suite – the integration layer• Oracle WebCenter – the Web 2.0 portal layer

The Challenge

O id• On one side:• JSF, EJB, Ajax, JavaScript, BPEL, SOAP, WSDL, RMI, JNDI,

JDBC, O/R, HTML, DOM….JDBC, O/R, HTML, DOM….

• On the other side:• Thousands of developersp• 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• Need to focus on their specific application needs

• How do you make it easy and approachable?

B id Obj t R l ti l• Bridge Object-Relational gap• Manage CRUD operations

Q i /DML• Queries/DML

• Implement business rules• Data validation• Data validation• Business logic

• ReusableReusable• Standards-based

ADF Business Components

A framework that simplifies developing Java EE business services for developers familiar with 4GL tools, declarative development, and relational databasesdatabases

Simplify data access• Simplify data access• Simplify validation and business logic

U SQL b d d t i• Uses SQL based data views• Separate data views from business logic

I l t b t ti• Implement best practices• Easy customization

ADF BC - Making Things Simpler

Q er b e ample an field• Query by example any field• Master/Detail coordination• List of valuesList of values• Calculated fields• Various validations• Exposing services• Range fetching

Transaction control• Transaction control• Locking mechanism• State managementg• All done declaratively without coding!

ADF BC Familiar Concepts for Forms/4GL Developers

D l ti DB d fi iti i il t bl k• Declarative DB access definition – similar to blocks• Built in events – similar to triggers in Forms

D l ti t tti f tt ib t• Declarative property setting for attribute• Declarative validation• Declarative LOV• Declarative calculated fields• Built in query by example• Find/Execute query support• Reusable property sets• Transaction management using commit/rollback
