Object Invocation and Management in Distributed Multimedia Systems

Future object management systems will need to provide support for a new class of applications: distributed multimedia design environments. Such environments pose new challenges for object management systems, requiring the integration of object-oriented techniques, distributed systems and multimedia technologies. To meet these challenges a flexible approach to object management is required. We demonstrate how such flexibility can be achieved without incurring undue management overheads by considering the implementation of three key features of a distributed object-oriented system: persistence, object migration and access control. 1. INTRODUCTION This paper describes work carried out as part of the Zenith project 1 aimed at producing a platform to support distributed multimedia design environments. Such environments, which include Office Information Systems, Geographical Information Systems and Integrated Project Support Environments, have a number of common requirements, including the n..
