Abstract: Most of research work concering software component technology has been focusing on the problems such as component manufacturing,storing,retrieving,tailoring and composing,which are also more often than not unduly emphasized,while pay less attention to a very important issue of how to exchange information and cooperate effectively and efficiently among component producers and component consumers.Proceeding from this consideration and motivation,this paper presents an implemented Internet based information system for software component and discusses the design concepts,the model and their realization.
