Oracle ADF is a service-oriented framework that allows developers to create Java EE applications across desktop, mobile, and web using the same services and security solutions. ADF utilizes JSF to allow for modular user interfaces using over 150 ready-to-use components. One of its most useful features is ADF Business Components, which provide pre-made code modules that greatly expedite development setup and handling of basic functionality. Using ADF advantages our project by providing a robust and maintainable application based on standards with increased productivity.

1. An Overview of Oracle ADF and How Our
Project Can Benefit from Usage
Oracle ADF (ApplicationDevelopmentFramework) isaService-OrientedArchitecture (SOA) framework
for creatingJavaEnterprise Edition(JavaEE) applications.ADFworksasa cross-platformsolutionthat

Advantages of using ADF
 It supports Rapid Application Development.
 It is based on MVC architecture
 Declarative Approach (XML Driven)
 Secure
 Reduces maintenance cost and time
 SOA Enabled
 Increase Productivity & ease of use
 Promote service-oriented development
 Standards based (Java EE, SOA, SDO/SCA)
 End to end coverage like (MVC, security, customization

2.  providing robust, performant, and maintainable applications
 Application Module manages transaction.
 We write validations at Entity Object level, because they provide highest degree of reuse
Various components in ADF
 ADF Business Components: VO, EO & AM
 ADF Model: DataBinding (.cpx, .xml) & DataControls(.dcx)
 ADF View: JSP, JSF, ADF Faces etc.
 ADF Controller: Task flows (adf-config.xml), faces-config.xml
