Component-based software engineering or CBSE represents a new development paradigm: assembling software systems from components. This research area has raised a tremendous amount of interests both in the research community and in the software industry-a rare phenomenon in the field of software engineering. The paper discusses the technology infrastructure necessary to support CBSE. In particular, the authors present the results produced by the CBSE research project conducted at Andersen Consulting in the context of how their approach and tools automate a component-based development paradigm.
