The move towards Distributed (Multimedia) Systems, in particular in the
context of the Global Information Infrastructure and related applications,
has produced requirements for the integration of database systems into
distributed multimedia systems, with both modeling support and extended
database mechanisms support. Object-oriented technology provides a good
basis for such an integration. The ISO DIS 10746 Reference Model for Open
Distributed Processing (ODP), and distributed object technologies such
as OMG CORBA with extended multimedia support and high-speed communication
such as ATM, provide a good basis for the integration of database-oriented
modeling and services, but also put forward new requirements for modeling
and database support. Objective: The objective of OMODIS (phase I) is to
create basic research results within the domain of modeling for distributed
multimedia systems with emphasis on object-oriented modeling and Quality
of Service modeling, based on a distributed persistent object architecture.
We propose to extend the project with a phase II which delivers basic research
results within database support for distributed multimedia systems with
emphasis on transaction processing and object modeling & query processing.
The application domains we focus on are distributed teaching and project
environments, but the results will also be applicable in other application
domains that use distributed object technology.
Approach:
The approach of the project is to base the OMODIS developments on the partner's
earlier research in modeling and database systems in the context of a common
distributed object platform (UNISIP) and the requirements of distributed
teaching and project environments. Phase I of the project will focus on
modeling for distributed multimedia systems, while phase II will extend
the project with additional database support for distributed multimedia
systems. Results and dissemination: The expected results will be published
at international conferences and in international journals. The main goal
of the project is to produce at least four publications each year from
the second year on, with a total minimum of 16 publications. The project
will result in two new doctoral degrees from phase I, and possibly two
more for the proposed extension in phase II. Exploitation of the results
will be conducted through application oriented projects at SINTEF and UNIK,
and through cooperation with Norwegian industry.
