Abstract In this paper we present a new rule-based approach for consistency preserving view updating in deductive databases. Based on rule transformations performed during schema d...
Given an intensional database (IDB) and an extension database (EDB), the view update problem translates updates on the IDB into updates on the EDB. One approach to the view update...
Bidirectional transformation is a pair of transformations: a view function and a backward transformation. A view function maps one data structure called source onto another called...
