Derived Data Update in Semantic Databases

The derived data update problem involves the transformation of modifications of derived facts into corresponding changes to base facts and other derived facts. Using a database schema defined with a generic semantic database model which includes derived data specifications, techniques and algorithms are provided for appropriately modifying base data when derived data are changed. An experimental prototype system based upon this approach has been developed.
