Abstract

With the increasing amount and diversity of information available on the Internet, there has been a huge growth in information systems that need to integrate data from distributed, heterogeneous data sources. Incrementally maintaining the integrated data is one of the problems being addressed in data warehousing research. This paper presents an incremental view maintenance approach based on schema transformation pathways. Our approach is not limited to one specific data model or query language, and would be useful in any data transformation/integration framework based on sequences of primitive schema transformations.
