基于模型驱动架构的数据库重构

Database Re-engineering Based on Model Driven Architecture

针对交叉使用数据库重构方法较为困难的问题,提出一种基于模型驱动架构(MDA)的通用数据库重构框架,其中包括数据库重构中的元模型定义和模型转换定义,并采用EMF和Operational QVT构建工具,该框架利用MDA的模型转换能力实现了数据库重构的自动化。

Database re-engineering is an important part in evolution of enterprise system.Some approaches have been developed in the field of database re-engineering.This paper proposes a Model Driven Architecture（MDA） based unified approach to combine these approaches together.The meta-model involved in the approach is defined,and so is the model transformation between these models.We develop a tool to implement this approach using EMF and Operational QVT,and achieve the automation of database re-engineering.
