Information integration with attribution support for corporate profiles
1999
The proliferation of electronically available data within large organizations as well as publicly available data (e.g. over the World Wide Web) poses challenges for users who wish to efficiently interact with and integrate multiple heterogeneous sources. This paper presents CI 3 , a corporate information integrator, which applies XML as a tool to facilitate data mediation and integration amongst heterogeneous sources in the context of financial analysts creating corporate profiles. Sources include Lotus Notes, relational databases, and the World Wide Web. CI 3 applies a unified XML data model to automate integration. By preserving metadata about the source of each datum in the integrated result set, CI 3 supports source attribution. Users may trace the attribution metadata from the result back to the underlying sources and leverage their expertise in interpreting the data and, if necessary, use their judgment in assessing the authenticity and veracity of results. We present a functional overview of CI 3 , its system architecture including the XML data model, and the integration procedures. We conclude by reflecting on lessons learned.
