MDA：模型驱动架构 [英] MDA : Model Driven Architecture

问题描述

需要一个开发非常简单的应用程序来展示MDA概念的想法。

Need a idea for developing very simple application demonstrating concepts of MDA.

推荐答案

好的，很难找到类似的东西MDA致力于解决更大问题的MDA世界中的一个问候世界。我认为开始的最好方法是通过思考meta- 模型来解决下面的问题

Alright, it is hard to find something analogous to a hello world in MDA world as MDA is geared on solving a bigger problem. The best way in my opinion to get started is to approach the below problem by "thinking in meta-model"

在任何实际的应用程序中，您需要保留任何业务实体所需的某些工件。挑选2个像Customer和Orders这样的简单实体，并在任何多层应用程序的所有层（如ui，持久性等）中生成所有相应的工件。以下是开始使用的工件

In any real world application, there are certain artifacts that you require for any business entity to be persisted. Pick 2 such simple entities like Customer and Orders and generate all the corresponding artifacts across all the layers of any multi-tiered application (like ui, persistence etc). Below are the artifacts to get you started

1. UI（jsf表单，托管bean，
   faces-congig.xml） user to
   输入两个实体的数据


2. Servie后来的工件，如
   交易分界码等


3. 持久层工件如
   （DAO / Repository，JPA / Hibernate
   映射文件）

现在，您还将确定还有更多的东西需要建模，比如faces-config，jpa / hibernate config等。

Now in the process you will also identify that there are more things to model like faces-config, jpa/hibernate config etc..

EMF 是用于元模型的更普遍的工具包，并且 oAW 是您的生成/转换引擎。 本教程可以帮助您入门。

EMF is the more prevalent toolkit for meta-modling and oAW is your generation/transformation engine. This tutorial can get you started.

Spring Roo 和 OpenXava 在我看来是两个众所周知的支持MDA的框架

Spring Roo and OpenXava are in my opinion two well know frameworks that supports MDA

准备好在元模型，元元模型，模型实例等的MDA术语中松开自己......
