"Bean Validation standardizes how to define and declare domain model level "
"constraints. You can, for example, express that a property should never be "
"null, that the account balance should be strictly positive, etc. These "
"domain model constraints are declared in the bean itself by annotating its "
"properties. Bean Validation can then read them and check for constraint "
"violations. The validation mechanism can be executed in different layers in "
"your application without having to duplicate any of these rules "
"(presentation layer, data access layer). Following the DRY principle, Bean "
"Validation and its reference implementation Hibernate Validator has been "
"designed for that purpose."

"The integration between Hibernate and Bean Validation works at two levels. "
"First, it is able to check in-memory instances of a class for constraint "
"violations. Second, it can apply the constraints to the Hibernate metamodel "
"and incorporate them into the generated database schema."

"Each constraint annotation is associated to a validator implementation "
"responsible for checking the constraint on the entity instance. A validator "
"can also (optionally) apply the constraint to the Hibernate metamodel, "
"allowing Hibernate to generate DDL that expresses the constraint. With the "
"appropriate event listener, you can execute the checking operation on "
"inserts, updates and deletes done by Hibernate."
