Interoperable Databases Mike P. Papazoglou, Alex Delis fmikep,[email protected] School of Information Systems Queensland Univ. of Technology Brisbane, QLD 4001, Australia Bernd J. Kramer [email protected] Data Processing Technology FernUniversit at Hagen 58084 Hagen, Germany Abstract Many contemporary inter-networked databases simply co-exist and act in isolation. The participating systems are typically heterogeneous since they have been developed under di erent usage models, data modeling formalisms and platforms. Yet, there is an ever increasing demand to create a uni ed database system in such a way that users can have e cient access to distributed information resources. In this paper we present an architectural framework that can assist in building such coherent aggregates of database systems. Key features of this framework nd their origin in distributed environments such as the OSF's DCE, OMG's OMA, and the ANSAware. However, we augment these features in order to facilitate intricate inter{database operations and negotiation.

Functionalities in Grid Computing with Active Services
In this paper we discuss architectural aspects of middleware for grid computing based on an infrastructure of distributed clusters and/or distributed services, an access portal for a demonstration project in progress, and also some security issues. We observe, in recent works, activities in the direction of open service architectures for grid services and for web services. We also see advantage...
متن کاملEnhancing Availability of Cooperative Applications Through Interoperable Middleware
Cooperative information systems are characterized by distribution, high heterogeneity and scale. Therefore they require interoperable, dependable services on top of which the development of cooperative application can take place. This paper studies, in the context of the Unitary Network of the Italian Public Administration, the problem of increasing the availability of the services exported by ...

We describe a novel semantics-based architecture for standards-based approaches to interoperable applications. The paper includes our experiences in prototyping the proposed architecture and demonstrating the resulting semantic middleware capability. This capability enabled legacy applications with heterogeneous interfaces to communicate in an interoperable fashion. An industrial scenario was u...

متن کاملAccess control in ultra-large-scale systems using a data-centric middleware
The primary characteristic of an Ultra-Large-Scale (ULS) system is ultra-large size on any related dimension. A ULS system is generally considered as a system-of-systems with heterogeneous nodes and autonomous domains. As the size of a system-of-systems grows, and interoperability demand between sub-systems is increased, achieving more scalable and dynamic access control system becomes an im...
