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 6 Copyright © 2011, Oracle and/or its affiliates. All rights reserved. ADF BC - Making Things Simpler • 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! 7 Copyright © 2011, Oracle and/or its affiliates.
