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
Target Audience
Managers
AJAX developers
Non-AJAX developers & Oracle PL/SQL developers
End-Users…waiting impatiently for the benefits of
Web 2.0 @ Work
Our Philosophy
It’s All About the End User
Rich Web Applications
Yahoo Mail
Zimbra
App generated from Oracle DB
Google Docs
What makes a Web Application “Rich”?
FLASH
FLEX
AIR
AJAX
All provide amazing interactivity
AJAX
Asynchronous JavaScript and XML
A popular technique for providing rich application features
AJAX is a group of inter-related Web development scripting
languages (including JavaScript, PHP, etc) used for creating
interactive Web applications
AJAX
More Philosophy
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.

The Database
XML
AJAX
Flash
JSON
Build it in the database?
Doesn’t that fly in the face of conventional system architecture?
Distribute the application
Database Independence
Model View Control (MVC)
And so on…
The Flip Side…
Middle-tier developers spend enormous amounts of time
recreating functionality already provided by the database
Methods
Classes
Objects
Constructors
Connection Pooling
Think about this…
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?”

Why Thick Database?
Harness power and performance of Oracle
Eliminate the “middle-tier” tax
network congestion and latency between App and Database servers
slow ODBC/JDBC calls
Multiple steps handling the data
unparsed and un-tuned SQL statements
Utilize Oracle features for scalability
Lower cost of ownership by leveraging existing
Oracle investment and staff skills
Use PL/SQL to serve up AJAX and FLASH features
Why Thick Database? (cont.)
Application code is stored in compiled packages in
the database for fastest performance
One backup and recovery process for both
application and data
Rapid deployment and enhancements
Smaller development team
Get more value out of your Oracle DB investment

Live Demo for Developing RIA applications
from the ORACLE database
Benefits of combining AJAX & Database
Leverage Oracle features for scalability and performance
Build Enterprise-class Rich Web Apps right out of the
database using existing skills and infrastructure
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
Flexible and open standard for customization and third
party tool integration
