5 Copyright © 2011, Oracle and/or its affiliates. All rights reserved. ADF Business Components Database Access Layer A framework that simplifies developing Java EE business services for developers familiar with 4GL tools, declarative development, and relational databases

• Simplify data access • Simplify validation and business logic • Uses SQL based data views • Separate data views from business logic • Implement best practices • Easy customization

• Query by example any field • Range fetching • Master/Detail coordination • Web service interfaces • List of values • Transaction control • Calculated fields • Locking mechanism • Various validations • State management

All done declaratively without coding!

*ADF also does dependent LOVs

• Examples: • Get translation to code – Usually coding in postquery or WhenValidateItem – ADF no code needed (joined view) • Masterdetail synchronization over Forms – Forms Requires parameter passing – Automatic in ADF

• Groovy Script expressions • Even simpler syntax than Java

if ( FirstName=="Lex" && newValue > 5000) { return false } else return true

• Over 150 components • Ajax enabled • Pluggable look and feel • Accessibility & internationalization • The usual components plus: – Charts, gantt, geomap, pivot, calendars, coverflow • Built in advanced functionality: – Drag and drop framework – Dialog and popup framework – “Active Data” Dashboards / push updates (comet) – Templating and declarative components

• Forms – Absolute positioning – Easier to understand • ADF – Relative positioning – Better for changing screen sizes/resolutions – More layout styles – Templating

If process_submit then Call_Form (‘FormA’ ) Else Call_Form (‘FormB’); End if;

• Layered approach to changes • Single base application for all users • Upgrades safe
