Data integration with dependent sources
2011
Proceedings of the 14th International Conference on Extending Database Technology - EDBT/ICDT '11
Preserved Fulltext
Data integration systems offer users a uniform interface to a set of data sources. ...
of dependent sources, where some sources copy parts of their data from others. ...
System We are building a system called IDS (Integrating Dependent Sources), for integrating a large number of data sources, where dependencies may exist between sources. ...

Based on this model, we explore extensions to data integration systems called behavioral dependency, a formal notion that captures the dynamic interactions between the control applications. ...
More formally, a data integration system is defined as I = G, S, M , with a global schema G, semantic mappings M, and data sources S. ...

IBIS adapts and integrates the data extracted from the sources making use of the constraints in the global schema, so as to answer queries at best with the information available. ...
IBIS deals with limitations in accessing data sources, and exploits techniques developed for querying sources with access limitations in order to retrieve the maximum set of answers. ...
In order to assign semantics to a data integration application I = G, S, M , we start with the data at the sources, and specify which data satisfy the global schema. ...
