Warehousing Approach to Data and Knowledge Integration

摘要

The topic of data warehousing encompasses architectures, algorithms, and toolsfor bringing together selected data from multiple databases or other information sources into a repository, called a data warehouse, suitable for direct querying or analysis. The objective of this effort was to provide a mechanism for rapidly and effectively integrating data and knowledge from multiple, diverse, information sources, and to provide a simple way for clients to locate, retrieve, and exploit the relevant integration information quickly and efficiently. Within this effort the goals were to develop the specification languages, algorithms, and techniques necessary to realize a warehousing approach to data and knowledge integration, to demonstrate the techniques in a software prototype, and to validate the utility of the approach with a suite of sample applications.
