1.6. Summary
In this chapter, we introduced the concepts around which JDO is centered: a standard specification for incorporating persistence facilities into Java applications. We looked at how JDO provides an API that gives developers a Java-centric view and insulates the application code from the complexities of the underlying datastores. We also looked at the how JDO has been designed to fit into the non-managed and managed environments and the logical roles and responsibilities of the different parties involved.
In the next chapter, we write our first JDO application and introduce you to development with JDO.
