Model　Driven　Architecture　(MDA)　is　a　model-centric　software　development　method,　models　and　model　transformation　are　core　technology　of　the　MDA.　The　key　of　achieving　MDA　is　to　create　Platform　Independent　Model　(PIM)　and　Platform　Specific　Model　(PSM),　define　the　transformation　rules　from　PIM　to　PSM.　The　paper　based　on　the　MDA　ideas,　designs　how　to　get　a　database　model　automatically　by　model　transformation,　and　then　analyses　the　Atlas　transformation　method　and　its　characters.　Finally,　we　introduce　an　example　of　how　model　transformation　system　generates　the　target　model　automatically,　and　to　some　extent,　to　verify　the　feasibility　of　the　MDA　in　the　software　development.　©　2012　IEEE.
