Abstract:

Based on MVC framework, the authors designed and used meta object facility of the fourtiered management structure model for object modeling tools, with the help of twostage model theory, to divide the traditional modeling work into element construction model and the traditional model in two stages. After analysis of specific areas, domain modeling can be realized by means of the improved XKL domain modeling language from meta object facility metalanguage.

Key words: model driven architecture(MDA), meta object facility(MOF), twolevel modeling
