Course Overview

TopLink is Oracle's Object-Relational Mapping Engine, a tool which allows the application developer to work with data in a relational database while working purely in Java. This course presents a comprehensive introduction to TopLink's visual workbench and its rich feature set via a series of hands-on tutorials. Delegates will use JDeveloper to rapidly build and deploy TopLink applications based on complex table relationships and to write objects to the database and to retrieve objects using TopLink's Query Framework. Additionally, delegates will learn to use TopLink's transactional capabilities and learn to tune applications for performance with its caching facility.
