Database Re-engineering Based on Model Driven Architecture

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.
