如何保持N层架构交易 [英] How To Maintain Transaction in N-Tier Architecture

问题描述

我开发的N层体系结构的应用程序。因为我们都知道，我们需要实现的事务，同时插入/更新/删除操作。请告诉我如何在N层架构使用C＃.NET交易。
我的建筑是这样的
Applicationform-> middle_Layre->厂 - > DataAccessLayre-> StoredProcedure->表
申请表我创建middleLayer的对象，并在插入/更新的数据传递/删除中间层的功能。
我创建的factoryclass的SqlCommand对象，并填写这是我从中间层获得的数据和对象OS的SqlCommand传递给DAL。

I am developing application in N-Tier Architecture. as we all know that we need to implement transactions while insert/update/delete operation. please tell me how to use transaction in c#.net in N-Tier architecture. my architecture is like this Applicationform->middle_Layre->Factory->DataAccessLayre->StoredProcedure->Table in application form i create object of middleLayer and pass data in Insert/update/delete function of middle layer. i am creating object of sqlcommand in factoryclass and fill the data which i gets from middle layer and pass that object os sqlcommand to DAL.

推荐答案

下面是一个软件层重新presentative模式可以遵循：

Here is a representative pattern of software layers you can follow:

Database <-> DAL <-> Repository <-> BLL <-> Controller <-> View Model <-> UI

其中，

DAL == Data Access Layer (aka ORM, Object-Relational mapper)
BLL == Business Logic Layer*

在此模型中，交易发生在Repository，其中布置一个工作单元。通常情况下，这种情况从DAL请求数据，对其执行工作，并保存更改。该DAL一般会环绕你的工作单位的事务。

In this model, the transaction takes place in the Repository, where a "unit of work" is arranged. Typically, this happens by requesting data from the DAL, performing work on it, and saving changes. The DAL will generally wrap a transaction around your unit of work.

数据库，DAL，库和BLL共同形成所谓的MVC（模型 - 视图 - 控制器）架构模型。所有的业务逻辑和数据处理发生在模型中。该控制器充当穿针引线的模型和视图模型/ UI，它们共同形成视图之间。

The Database, DAL, Repository and BLL collectively form what is known as the Model in MVC (Model-view-controller) architecture. All business logic and data manipulation takes place in the Model. The controller acts as a go-between between the model and the View Model/UI, which collectively form the view.

该库是您将设置你的工作单元。

The Repository is where you would set up your "Unit of Work."
