Using Schema Transformation Pathways for Incremental View Maintenance
In heterogeneous data warehousing environments, autonomous data sources are integrated into a materialized integrated database. The schemas of the data sources and the integrated database may be expressed in different modelling languages. It is possible for either the data or the schemas of the data sources to be updated. Incremental view maintenance 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/intergration framework based on sequences of primitive schema transformations.
