22   * Root of the hierarchy of data access exceptions discussed in
23   * <a HREF="http://www.amazon.com/exec/obidos/tg/detail/-/0764543857/">Expert One-On-One J2EE Design and Development</a>.
24   * Please see Chapter 9 of this book for detailed discussion of the
25   * motivation for this package.
26   *
27   * <p>This exception hierarchy aims to let user code find and handle the
28   * kind of error encountered without knowing the details of the particular
29   * data access API in use (e.g. JDBC). Thus it is possible to react to an
30   * optimistic locking failure without knowing that JDBC is being used.
31   *
32   * <p>As this class is a runtime exception, there is no need for user code
33   * to catch it or subclasses if any error is to be considered fatal
34   * (the usual case).
