问题描述

其实我pretty困惑这个术语，以及它们如何相互关联的。一个读一些了其中的每个人，但我不uderstant工作流程。

Actually i'm pretty confused about this terms and how they relate to each other. A read something about every one of them but i don't uderstant the work flow..

DTO - 数据传输对象 - 对象传输值

BO业务对象 - 域模型对象。反对使业务逻辑与

POCO - 不知道，我读过关于维基的定义，但没有什么了解

道 - 数据访问对象 - 对象映射数据库表？

DTO - Data transfer object - object to transport values
BO Business object - object in domain model. object to make Business logic with
POCO - no idea, i've read a definition on wiki but didn't understood anything
DAO - data access object - object to map the DB table ?

可能有人请带来一些光进入它我的？

Could someone please bring some light into it for me ?

推荐答案

• DTO ：数据传输对象，用来传输松耦合服务之间的数据


• POCO ：普通老式CLR对象，CLR正常对象不使用任何属性或要求继承充当DAO / DTO


• BO ：业务对象，包含业务逻辑，在解决方案的业务逻辑部分中使用


• DAO ：数据访问对象，用于将数据从数据库传输

• DTO: Data Transfer Object, used to transfer data between loosly coupled services
• POCO: Plain Old Clr Object, normal CLR object doesn't use any attributes or required inheritance to act as a DAO/DTO
• BO: Business Object, contains business logic, used in the Business Logic part of your solution
• DAO: Data Access Object, used to transfer data from your database

因此​​，一个普通的工作流程是从一个服务，该服务发送到您的应用程序作为DTO请求数据，将其转换为一个BO来操作它，并发送回一个DTO或将其转换为DAO店后它在数据库中。

So a regular workflow would be to request data from a service, which is sent to your app as a DTO, you convert it to a BO to manipulate it and send it back as a DTO or after converting it to a DAO store it in a database.

您使用不同的对象为3种类型之间的单独的担忧，一个BO并不需要知道无论是使用一个数据库或服务持续存在。

You use the different object to separate concerns between the 3 types, a BO doesn't need to know whether it's persisted using a database or a service.
