The presentation layer can call the validation logic on the data provided by a form before passing it to the domain model.
展示层可以调用验证逻辑对表单提供的数据进行验证，然后再将该数据传递给域模型。
The constraints are defined in the bean (domain object) so the validation logic is close to the domain model.
约束是定义在一个bean（领域对象）中的，因此校验逻辑离领域模型最近。
This paper shows a new domain in which constraint programming can be exploited as model verification and validation.
本文同时揭示了限制编程的一个新的应用领域模型验证。
