abstract
In both scientific research and data analysis, one of the most important challenges is managing and utilizing large amounts of data. Unfortunately, the information needed may be distributed across multiple databases with inconsistent or conflicting schemas. Such data inconsistencies are, at the very least, an impediment to users. This phenomenon raises the need for a tool that can integrate heterogeneous databases. This project established an architecture for integrating data from heterogeneous databases into an RDF data repository and then mapping the integrated dataset to concepts in an ontology. Through the concepts represented in the ontology, users can readily retrieve information from the federated data repository system.
