SemQL

Jeong-Oog Lee, Doo-Kwon Baik
1999 Proceedings of the eighth international conference on Information and knowledge management - CIKM '99  
An essential prerequisite to achieving interoperability in multidatabase systems is to be able to identify semantically equivalent or related data items in component databases.  ...  In this paper, we provide semantic networks so that multidatabase systems can detect and resolve semantic heterogeneities among component databases.  ...  Therefore the need for integrating disjointed databases became increasing. A multidatabase system provides integrated access to heterogeneous, autonomous component databases in a distributed system.  ...

A mediation layer for heterogeneous XML schemas

Abdelsalam Almarimi, Jaroslav Pokorny
2005 International Journal of Web Information Systems  
A global XML schema is specified by the designer to provide a homogeneous view over heterogeneous XML data.  ...  This paper describes an approach for mediation of heterogeneous XML schemas. Such an approach is proposed as a tool for XML data integration system.  ...  This work was supported in part by the National programme of research (Information society project 1ET100300419).  ...

Integration operators for generating RDF/OWL-based user defined mediator views in a grid environment

Abdel-Rahman H. Tawil, Adel Taweel, Usman Naeem, Matthew Montebello, Rabih Bashroush, Ameer Al-Nemrat
2014 Journal of Intelligent Information Systems  
These views support different perceptions of the distributed and heterogeneous data available. A set of grid services are developed for the implementation of the mediator views.  ...  This paper describes our approach to supporting semantic interoperability in a heterogeneous multi-information server grid envi-ronment.  ...  This saves the user the burden of considering large global schema to locate information from multiple distributed and heterogeneous servers.  ...

Naming Conflict Resolution in Multidatabase Systems using Bridge Table

Samia M., Rania A., Omer I.
2019 International Journal of Computer Applications  
here also comes the need for integrating already existing databases in one global database, due to the lack of integrated database many organizations make use of only a few parts of the collected data  ...  In some organizations there may be legacy systems that can't interact with each other, so these organizations can't make use of these systems unless they are integrated together in one global database,  ...  This conflict must be solve before getting a unified global schema then we must understand the semantics of the databases to integrate it effectively in heterogeneous distributed environment, in this thesis  ...
