3.15 Summary

After reading this chapter, you should understand what transparent persistence is all about and what it means when a Java class is persistence-capable. You have seen how to create, read, update, and delete persistent objects, and you have explored how JDO supports the full Java object model: basic types, references, collection classes, and inheritance. You should also understand some of the more advanced JDO concepts like handling exceptions, object identity, object lifecycles, and concurrency control.

In the next chapter, you learn more about the different states in the JDO object lifecycle and how the JDO implementation manages persistent objects in-memory.
