摘要: The Model Driven Architecture (MDA) represents a positive step toward general model-based approach to software engineering. conceptualization of the MDA is not yet mature; it still being formed. Elements modeling foundation are described in this paper, including an architecture engineering and multi-dimensional space that provides separation concerns systematic uniform models self-similar at all levels each dimension. position paper right way forward, but can be strengthened made more complete by incorporation some concepts proposed foundation. 1. Purpose content OMG has introduced as its next generation technology integration. Much work previously done readily incorporated into model-oriented approach. Furthermore, concept model driven generally applicable larger community, limited technologies. Therefore, strongly support thrust broader However, key supposition further strengthening for would beneficial realizing goals purpose describe engineering, indicate how strengthen MDA. proposes element
