Imagine the cost and risk of running dozens of instances of your most-revenue-critical hosted multi-tenant application in a legacy object-oriented database management system (OODBMS) technology from a vendor of questionable viability as your business grows. Imagine the management and technical challenges of changing the persistence approach in such a production application with an extremely complex domain model, billions of objects in the database, and highly polymorphic AI-based application logic from a Smalltalk OODBMS to Java and the Oracle relational database. This session will show how US Oncology met these challenges using Oracle Coherence and Oracle TopLink, a commercial distribution of the EclipseLink project.

Bob Bretthauer is an Application Development Manager at US Oncology.  He's played a lead role in the development and architecture of the iKnowMed electronic medical record since it was first released in 1997.  Over the past 20 years, Bob has worked on object persistence frameworks in C++, Smalltalk, and Java.  He's currently looking at ways to increase application scalability using EclispeLink and Coherence.

 

Shaun Smith is a Principal Product Manager for Oracle TopLink and an active member of the Eclipse community.  He's Ecosystem Development Lead for the EclipseLink project and a committer on the Eclipse EMF Teneo, and the Dali Java Persistence Tools projects.  He’s currently working on OSGi persistence and Oracle TopLink Grid, which integrates Oracle Coherence with EclipseLink JPA to provide “JPA on the Grid”.
