Integration of Distributed Services based on OSF DCE

Object-based approaches are suitable for implementing distributed system solutions; major reasons are provision of well-specified interfaces, global object identity, and implementability on top of more conventional client/server-style RPC systems. Significant results in this area have been achieved, and have made their way into industry standards. However, the relatively fine-grained, programming-in-the-small view of distributed object-based systems is not sufficient for future wide area, high performance networks with widely distributed services. A major requirement is that service-integration facilities based on extended object-based approaches are provided. We propose a system approach with a specific declarative language with graphical support, and an associated decentralized runtime system in order to address these problems. The major idea is to select, couple and execute existing, widely distributed services rather than implementing distributed applications from scratch. The desi..
