This document summarizes a presentation on Oracle Application Development Framework (ADF) and its business components (ADF BC). It discusses how ADF BC can expose database tables and views as Java services, and its features like transaction management, caching, validation and more. It provides examples of creating an ADF BC application using HR data, including defining entity objects, view objects, and a business service. It demonstrates consuming the application via a web service and creating an ADF Faces web page bound to the application data. The page includes interactive charts and tables with features like filtering, sorting, resizing and contextual popups for drill-down.

ADF in action – getting
(re)acquainted with Oracle’s premier

ADF BC
• Expose tables, views and custom SQL queries as Java Services
• Declarative
• Productive
• Very similar to Forms blocks
• Features
– Optimistic & pessimistic locking
– Transaction Management
– Pooling of database session connections
– Caching of queried and manipulated data
– Validation of data manipulations
– Enrichment of data fetched from the database
– Web session (state) management
– Oracle SQL comes naturally (sequence, return after DML, joins, BLOBs, PL/SQL,..)
– Master/detail coordination
ADF BC
