Fusionplex: resolution of data inconsistencies in the integration of heterogeneous information sources

Amihai Motro, Philipp Anokhin
2006 Information Fusion  
Fusionplex is a system for integrating multiple heterogeneous and autonomous information sources that uses data fusion to resolve factual inconsistencies among the individual sources.  ...  performance of their data, excluding from the fusion process data that are too old, too costly, or lacking in authority, or numeric data that are too high, too low, or obvious outliers; and, ultimately  ...  The conflict resolution module resolves data conflicts in each polytuple according to the appropriate resolution policies. First, each mono-attribute polytuple is resolved with a single value.  ...

The Pegasus heterogeneous multidatabase system

R. Ahmed, P. DeSmedt, W. Du, W. Kent, M.A. Ketabchi, W.A. Litwin, A. Rafii, M.-C. Shan

The Issues And Solutions Of Integrating DBMS To A Multi-DBMS

Leslie Leong
2011 Review of Business Information Systems (RBIS)  
We further extend to include issues in designing a MDBMS. With a MDBMS, data sharing across organization reduces overheads and costs, thus, provides a competitive advantage to the global firms.  ...  The objective of this paper is to introduce a multi-database system (MDBMS) that interacts with other heterogeneous DBMS within the organization to integrate information processing.  ...  The overall language of an MDBS for both data definition and manipulation was called a multidatabase language.  ...

Adding Conflict Resolution Features to a Query Language for Database Federations

Kai-Uwe Sattler, Stefan Conrad, Gunter Saake
2000 Australasian Journal of Information Systems  
During the integration phase these conflicts have to be identified and resolved as part of the mapping between local and global schemata.  ...  A main problem of data integration is the treatment of conflicts caused by different modeling of real-world entities, different data models or simply by different representations of one and the same object  ...  Resolving description conflicts by using a rule-based data conversion language is described in Cluet et al. (1998) , Milo & Zohar (1998) presents a schema-based data translation solution.  ...

Semantic heterogeneity resolution in federated databases by metadata implantation and stepwise evolution

Goksel Aslan, Dennis McLeod
1999 The VLDB journal  
We introduce metadata implantation and stepwise evolution techniques to interrelate database elements in different databases, and to resolve conflicts on the structure and semantics of database elements  ...  Schema implantation and semantic evolution, our approach to the metadata folding problem, is a partial database integration scheme in which remote and local (meta)data are integrated in a stepwise manner  ...  In the third key approach to the metadata folding problem (Fig. 4) , multidatabase systems offer multidatabase users with powerful multidatabase languages through which users can manipulate data in different  ...

Interbase-KB: Integrating a knowledge base system with a multidatabase system for data warehousing

N. Bassiliades, I. Vlahavas, A.K. Elmagarmid, E.N. Houstis
2003 IEEE Transactions on Knowledge and Data Engineering  
This paper describes the integration of a multidatabase system and a knowledge-base system to support the data-integration component of a Data Warehouse.  ...  The multidatabase system integrates various component databases with a common query language, however it does not provide capability for schema integration and other utilities necessary for Data Warehousing  ...  Resolution of schematic and semantic conflicts. After the homogenization of the data models, there is still a need to resolve the conflicts among the schemata of the data sources.  ...

Interactive example-driven integration and reconciliation for accessing database federations

Kai-Uwe Sattler, Stefan Conrad, Gunter Saake
2003 Information Systems  
At both levels a mapping from local elements to global elements is specified and various conflicts caused by the heterogeneity of the sources have to be resolved.  ...  This integration approach is supported by a multidatabase query language, which provides special mechanisms for conflict resolution.  ...  It is based on the multidatabase query language FraQL [1] , which extends SQL by advanced conflict resolution mechanisms.  ...
