Rich Web Applications for the Enterprise...Creating RWA from Your Oracle Database

Presented By:John KrahulecBizwhazee

SEOUC Charlotte February 2009

Learn how PL/SQL Developers can deliver Rich Web Applications (RWA) directly from the Oracle database

Build apps far more sophisticated than previously thought possible using the PL/SQL web toolkit as a foundation

No complex middle-tier setup

Achieve technology efficiency by serving AJAX features directly from PL/SQL APIs

Managers

Non-AJAX developers & Oracle PL/SQL developers

AJAX developers

End-Users… waiting impatiently for the benefits of Web 2.0 @ Work

It’s All About the End User

AJAX

All provide amazing interactivity

FLASHFLEX AIR

A popular technique for providing rich application features

Asynchronous JavaScript and XML

AJAX is a group of inter-related Web development scripting languages (including JavaScript, PHP, etc) used for creating interactive Web applications

AJAX is a game changer

Software development should be getting easier

Combine AJAX with PL/SQL for the ultimate application development environment for the Enterprise.

Build it in the database?

Doesn’t that fly in the face of conventional system architecture?

Distribute the application

Database Independence

And so on…

Model View Control (MVC)

The Flip Side…

Middle-tier developers spend enormous amounts of time recreating functionality already provided by the database

What is the probability that UI languages will be the same next year?

What is the probability that your database will be the same next year?

“So why not leverage the database as the foundation of our Rich Web App development approach?”

Utilize Oracle features for scalabilityLower cost of ownership by leveraging existing Oracle investment and staff skills

network congestion and latency between App and Database servers

Harness power and performance of Oracle

Use PL/SQL to serve up AJAX and FLASH features

Eliminate the “middle-tier” tax

slow ODBC/JDBC calls

unparsed and un-tuned SQL statements

Multiple steps handling the data

Application code is stored in compiled packages in the database for fastest performanceOne backup and recovery process for both application and data

Rapid deployment and enhancementsSmaller development team

Benefits of combining AJAX & Database

AJAX and Flash stored in the database

Just use PL/SQL to call the APIs to build RWA components Authenticated AJAX calls from browser to database

Build Enterprise-class Rich Web Apps right out of the database using existing skills and infrastructure

Leverage Oracle features for scalability and performance

Flexible and open standard for customization and third party tool integration
