Abstract
Federated database systems are heterogeneous with
respect to data models and query languages but also with
repect to underlying operating systems and hardware
platforms. Besides transformations on the semantic level
conversions on the data representation and communication
protocol level have to be done. In this paper, we present the
Remote Cooperation System RCS which provides client/server
communication procedures independent of hardware
and operating system aspects. Thus, the configuration of a
system may change without affecting theparticipating
databases and application tools. The RCS allows for asynchronous
service invocation, thus enabling the simultaneous
querying of several databases by one application. Further
more, it supports multi-tasking of server processes and the
element-wise transfer of results. Monitoring tools allow the
assessment of several choices in system configuration and
access algorithms embodied in the application processes.
