    Presentation Overview

    First Talk: Overview of Java Data Objects and Versant Open Access JDO



    Robert Greene, Director, Systems Engineering Versant Corporation



    Overview of Java Data Objects. Specifically, how JDO can be used to solve issues related to OR-Mapping both inside and outside of managed environments. We will see an example of JDO's mapping capabilities built into the "Versant Open Access - JDO" solution by converting an in memory application to one that is working with a relational database. During the conversion we will discuss each of the specifics of a persistence implementation using JDO. We will then open the discussion to how a JDO solution compares with other technologies like EJB 3.0, Hibernate, TopLink, etc.





     

    Second Talk: Transactions in JDO



    Richard Taylor, Kernel Architect IBM Silicon Valley Lab



    JDO provides transparent persistence of your Java object models in transactional datastores. In practice this means that you can have persistent objects in Java without having to know, understand or deal with databases. However, JDO does not hide transactions, and you do need to understand transactions to use JDO properly. This talk will tell you what you need to know about transactions, including explaining such mysteries as transaction isolation levels and what optimistic transactions are. We will also talk about how to structure applications to make them work well in a transactional environment.
