我将运用实体框架和世界合作框架。 正如我所看到的那样,所建议的做法是利用有实体框架的POCO,并利用POCO课程作为数据查询。 事实上,如果我不错的话,那么就使用了POCO和 Attributes。
但 要求我使用实体框架、POCO和WCF数据合同的适当类别。 并且使用POCO和数据合同之间的地图。 同FooContract, 具有相同特性。
我是第一种做法,但我想知道,第二种办法(妥善的班级办法)是否为应用提供了灵活性,还是只是浪费努力。
请大家分享您关于为POCO和数据查询、制作和整理而使用适当课程的想法和经验。
在持久性层面和合同一级有不同的数据类别,使你具有最灵活度。 例如,你可能不想暴露你在合同上的所有持久性领域,或想暴露出与合同不同的数据等级等。 它还允许相互独立改变。
首先,在两个层次上使用不同班级似乎是重复的,但从长远来看,工作并不多(与你所表现出的灵活性相比)。 在需要时,你可能会使用相同的班级,并发展不同的班级,但与这一办法有关的问题是,在短时间内,你的服务会紧跟数据班,而不是信息/数据,即服务应当与服务打交道。
