5 Summary

We presented a lightweight system that enables the access of various heterogeneous BES via the WWW (e.g. a Web browser). The object-oriented design establishes a framework that separates all communication aspects from the individual BES and provides an uniform GUI with general interfaces to the underlying BES and several application management facilities. Communication problems (scalability and limited bandwidth) are solved at the framework level in order to enable excessive reuse of the system's components for a rapid integration of BES. The communication components of the framework together with the loosely coupled BES lead to a lightweight, message-oriented information system that is especially useful in an environment like the WWW where an unpredictable number of users want to interact with various information sources.
