Paper Abstract:
|
An important application area in which software agents have an essential role to play is that of providing user access to a collection of heterogeneous distributed databases. This paper describes a general approach, which uses a multi-agents system based on Web services and common object request broker architecture (CORBA) to retrieve information from a set of heterogeneous distributed databases and consolidate it, taking account of the syntactic and semantic differences between data sources. The system is dynamic in that the data sources accessed by the system can change with time. The ability of software agents to negotiate and co-operate with each other make them ideal candidates for this kind of system. Web services can move software agents to the Internet. The role of CORBA in such a system has been investigated. Initially CORBA was used to enable software agents to access each others' services - although this limits the flexibility of the system. A better solution is based on the use of Web services while CORBA is used as the technology to implement the business logic for the software agent, and will be exposed to the Internet using Web services. |
