Security for Distributed E-Service Composition [chapter]

Stefan Seltzsam, Stephan Börzsönyi, Alfons Kemper
2001 Lecture Notes in Computer Science  
Overview of the ObjectGlobe System ObjectGlobe distributes powerful query processing capabilities (including those found in traditional database systems) across the Internet.  ...  We present a comprehensive security architecture for extensible, distributed systems using the example of an Internet query processing service which can be extended by user-defined operators.  ...  The security level of network connections can be chosen dependent on the processed data.  ...

Process Calculi and Peer-to-peer Web Data Integration

Sergio Maffeis
2006 Electronical Notes in Theoretical Computer Science  
Peer-to-peer systems exchanging dynamic documents through web services are a simple and effective platform for data integration on the Web.  ...  Dynamic documents can contain both data and declarative references to external sources, in the form of links, service calls, or coordination scripts.  ...  In the ObjectGlobe system instead, the emphasis is on executing complex queries on distributed data sources by discovering what peers provide operators or data relevant to the task at hand, and then dispatching  ...

Database patchwork on the Internet

Reinhard Braumandl, Alfons Kemper, Donald Kossmann
1999 Proceedings of the 1999 ACM SIGMOD international conference on Management of data - SIGMOD '99  
Naturally, data processing requires three kinds of resources: the data itself, the functionality (i.e. database operations) and the machines on which to run the operations.  ...  Conclusion We have installed our system on several sites at the University of Passau and, for testing in a larger scale environment, at the University of Mannheim and the University of Maryland, CP.  ...  and try to sell these on the Internet.  ...
