Testing JPA-based
applications
Unfortunately we need to deal with the object relational (O/R)
impedance mismatch, and to do so you need to understand
two things: the process of mapping objects to relational
databases and how to implement those mappings.

Most Java applications need to store data in persistent storage, and typically this
storage is a relational database. There are many approaches to persisting the data,
from executing low-level
SQL
statements directly to more sophisticated modules
that delegate the task to third-party tools.
