Focusing on the poor reusability, weak concurrent processing capability, no cross-platform and other problems of traditional program model transformation system, this article applies SOA architecture and MDA thought to the program model transformation, and gives out the system function structure and logical architecture based on SOA and the design of basic and complex transformation service modules. Additionally, it takes analysis and discussion for meta-model-based program model transformation framework and adopts ATL model transformation method. The achieved system application indicates that the architecture method is featured of scalability, cross-platform and supporting concurrent processing etc.
