Secondly, the paper does research systematically on the basic theories of MDA, including MDA model architecture, Meta Object Facility, the mapping from metamodel to other formats and Common Warehouse Metamodel. The paper also analyzes detaily the definition, the basic rule and the characteristic of model transformation. Then a standard development flow based on MDA is put forward. The problems about parameterized mapping and partial round-trip engineering are discussed. From the discussion the most optimized method is pointed out.
