* Exception thrown when an attempt to insert or update data
* results in violation of a primary key or unique constraint.
* Note that this is not necessarily a purely relational concept;
* unique primary keys are required by most database types.
*
* Consider handling the general {@link DataIntegrityViolationException}
* instead, semantically including a wider range of constraint violations.
