1995 SIGMOD record  
METU INteroperable Database System (MIND) is a multidatabase system that aims at achieving interoperability among heterogeneous, federated DBMSs.  ...  MIND architecture is based on OMG distributed o b j e ct management model. It is implemented on top of a CORBA compliant ORB, namely, ObjectBroker.  ...  These properties provide the means to handle heterogeneity at the database level. Thus CORBA provides for an infrastructure for implementing a multidatabase system.  ...

Mobile agents for WWW distributed database access

S. Papastavrou, G. Samaras, E. Pitoura
1999 Proceedings 15th International Conference on Data Engineering (Cat. No.99CB36337)  
In this paper, we propose a new framework for Web-based distributed access to database systems based on Java-based mobile agents.  ...  However, the current commercial applet-based methodologies for accessing database systems offer limited flexibility, scalability and robustness.  ...  We also like to thank Mitsuru Oshima from IBM Tokyo for his valuable assistance in our initial efforts to 'master' the Aglets Workbench.  ...

Advanced query mechanisms for biological databases

I M Chen, A S Kosky, V M Markowitz, E Szeto, T Topaloglou
1998 Proceedings. International Conference on Intelligent Systems for Molecular Biology  
Users of a fixed form-based query interface are limited to performing some pre-defined queries providing a fixed view of the underlying database, while users of a free text query language-based interface  ...  Existing query interfaces for biological databases are either based on fixed forms or textual query languages.  ...  We are currently developing CORBA based interfaces for application communication.  ...

Object persistence in object-oriented applications

V. Srinivasan, D. T. Chang
1997 IBM Systems Journal  
There are three classes of solutions for implementing persistence in object-oriented applications: the gateway-based object persistence approach, which involves adding object-oriented programming access  ...  In this paper, we describe the major characteristics and requirements of object-oriented applications and how they may affect the choice of a system and method for making objects persistent in that application  ...  Acknowledgments Our thanks to the reviewers and the editor for giving us valuable comments.  ...

Integrating Snapshot Isolation into Transactional Federations [chapter]

Ralf Schenkel, Gerhard Weikum
2000 Lecture Notes in Computer Science  
This prototype system, which includes a federated transaction manager coined Trafic (Transactional Federation of Information Systems Based on CORBA), has been fully implemented with support for Oracle  ...  These contributions are embedded in a practical project that built a CORBAbased federated database architecture suitable for modern Internet-or Intranetbased applications such as electronic commerce.  ...  Such a setting is known as a database federation or heterogeneous multidatabase system.  ...
