4.10. Looking Ahead...

Once again, we added hundreds of lines of new code with no visible difference to the application. Hopefully you can appreciate what is transparent to the end userby layering your application correctly, you can make massive changes to the persistence tier while leaving your presentation tier virtually untouched.

We have one more iteration of the CarList example to get through before we move on to more exciting stuff. In the next chapter, we'll create a Hibernate DAO that drastically simplifies the object-relational mapping that we have to do by hand in the JDBC DAO. After that, we'll start adding some new functionality to the application, such as logging in and buying cars.
