Abstract
Web based Software system need to be constructed in a short period. For such situation we need system support to each development process activities. In this paper we propose a model driven development environment. It aims at supporting developer and project manager to do their tasks. The basic idea of this environment is that all artifacts are modeled in MOF as a metamodel and then metadata which is instance of the metamodel stored in the MOF repository. Since metadata is stored in the unified MOF repository, we can easily construct our proposed developer and project manager support functionalities. There are three functinalities in this environment, automated transformation, project management support functions such as impact analysis and coverage analysis, and consistency management. In this paper we will show what they are and how to implement them. In the last, we will show the future problems about this environment.
