This market space is not without problem. A main problem is the difficulty of finding relevant offers. We present two possible solutions to this problem: Bon Marché and Logistics Agents which were developed with IBM’s Aglet Workbench – a particular implementation of mobile agents. This paper also surveys the agent technology and discusses the different agent building packages available on the market. Finally, it concludes that the future of local interaction, reduced network loading, server flexibility and application autonomy which are supported by mobile agent technology all help to provide a level agility above distributed problem solving.

However, this phenomena offers great promise for obtaining and sharing diverse information conveniently, but they also present a serious challenge. The sheer multitude, diversity, and dynamic nature of on-line information source makes finding and accessing any specific piece of information extremely difficult. The mobile agent technology provides an alternative way to assist the user in finding relevant Web based information. The use of mobile agents in this kind of applications represents a novel approach and potentially solves most of the problems that exist in centralized client-server solutions, because they are programs with a persistent identity which moves around a network and can communicate with this environment and other agents. We present a possible solution for this problem: the Data Agent system-a mobile agent application for the retrieval of distributed structured information in a scenario of several online bookstores. This system was developed for Web-based distributed access to database systems based on Java-based mobile agents. This paper describes the project architecture and its implementation that is based on IBM´s Aglets Workbench. It also emphasizes the obtained results with the several experiments realized, concluding that the implementation of the system shows that its performance is comparable to, and in some case outperforms the current approach.
