From Object-Oriented Conceptual Modeling to Component-Based Development

Conventional OO methodologies have t o p r o vide a well-deened Component based development CBD process by which the community of software engineers could properly derive executable software components from requirements in a systematic way. The move t o ward CBD requires existing OO conceptual modeling approaches to be reconsidered. In this paper we present a proposal to support CBD in an OO Method based on a formal OO model. The key element of this proposal resides on the concept of execution model. The execution model deenes a model and an architecture that provides a pattern to generate software components from OO conceptual models. Conceptual modeling patterns have a corresponding software representation in the quoted component-based architecture. The implementation of these mappings from problem space concepts to solution space representations opens the door to the generation of executable software components in an automated way.
