Abstract: 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.

Key words: database re-engineering, Model Driven Architecture(MDA), Eclipse Modeling Framework(EMF), Operational QVT

摘要： 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。
