| Popis: | 89 In the age of e-business, electronic marketplace provides a virtual trading place where demand and supply are more visible and trading efficiency is improved due to better liquidity. In this thesis, the author presents a system architecture for utilizing catalog-search agents to offer purchasing services through e-marketplaces. Catalog-searching services have been identified as one of basic services since e-marketplaces emerge as alternatives to traditional trading channels. Mobile agents, or software agents serving the purchasing function, have been identified as an approach to design e-procurement systems. In this thesis, the author applies the idea of mobile agents to catalog searching and presents a broad and innovative view of the system. In the system, XML is introduced as a standard for information exchange. Product information in catalog databases is designed to comply with the standard. As a result, asynchronous operations are feasible and extra effort to prevent inconsistency between local and remote programs can be reduced. The XML standards enable mobile agents to access catalogs on different platforms. The architecture presented can be classified as a type of three tiers. Examples are given to illustrate the functioning of this architecture. The benefits of this design include processing efficiency, lower utilization of resources, and low data transformation cost. |
