An Approach to Resolve Data Model Heterogeneities in Multiple Data Sources

C. Chirathamjaree
2006 TENCON 2006 - 2006 IEEE Region 10 Conference  
To interoperate data sources which differ structurally and semantically, particular problems occur, for example, problems of changing schema in data sources will affect the integrated schema.  ...  To gain a competitive advantage, it is imperative for executives to be able to obtain one unique view of information, normally scattered across disparate data sources, in an accurate and timely manner.  ...  Multi-database manipulation languages, which are capable of managing semantic conflicts through their specification, are provided as query language tools that are able to communicate with the local databases  ...

A survey of techniques for achieving metadata interoperability

Bernhard Haslhofer, Wolfgang Klas
2010 ACM Computing Surveys  
Achieving uniform access to media objects in heterogeneous media repositories requires dealing with the problem of metadata interoperability.  ...  Based on our work, domain experts and technicians get an overview and categorization of existing metadata interoperability techniques and can select the appropriate approach for their specific metadata  ...  ACKNOWLEDGMENTS The authors would like to thank Wolfgang Jochum and Bernhard Schandl as well as our referees for their valuable comments on this paper.  ...

Semantic conflict resolution ontology (SCROL): an ontology for detecting and resolving data and schema-level semantic conflicts

S. Ram, Jinsoo Park
2004 IEEE Transactions on Knowledge and Data Engineering  
Establishing semantic interoperability among heterogeneous information sources has been a critical issue in the database community for the past two decades.  ...  Despite the critical importance, current approaches to semantic interoperability of heterogeneous databases have not been sufficiently effective.  ...  Their valuable comments and suggestions greatly improved the quality of this paper.  ...

Resolving Schematic Discrepancy in the Integration of Entity-Relationship Schemas [chapter]

Qi He, Tok Wang Ling
2004 Lecture Notes in Computer Science  
In schema integration, schematic discrepancies occur when data in one database correspond to metadata in another.  ...  Although focusing on the resolution of schematic discrepancies, our technique works seamlessly with existing techniques resolving other semantic heterogeneities in schema integration.  ...  Previous works focused on the development of a multidatabase language by which users can query across schematic discrepant databases.  ...

Automatic query mapping among genomic databases: a pilot exploration

K H Cheung, P Nadkarni, P Miller, D G Shin
1998 Proceedings. AMIA Symposium  
As databases in the human genome project proliferate, it is important for users of one genomic database to identify similar or inconsistent data in other autonomously developed genomic databases.  ...  Our approach features two components: 1) a database designed to capture knowledge (metadata) that describes the correspondences among individual database components and 2) a module that utilizes the metadata  ...  GDB is a public repository featuring different kinds of maps (including physical, linkage, and radiation hybrid maps) for all human chromosomes.  ...

On the applicability of schema integration techniques to database interoperation [chapter]

Mark W. W. Vermeer, Peter M. G. Apers
1996 Lecture Notes in Computer Science  
We discuss the applicability of schema integration techniques developed for tightly-coupled database interoperation to interoperation of databases stemming from different modelling contexts.  ...  Both the local and the remote classifications of the appropriately merged instances are maintained, allowing for the derivation of a global class hierarchy if desired.  ...  Observe that such rules are able to deal with so-called schematic discrepancies [16] , as they describe instances rather than classes.  ...
