Basic Causes for the Inconsistency Tolerance of Query Answering and Integrity Checking
Hendrik Decker · 2010
Methods for query evaluation usually differ from methods for integrity checking, and even more so if they are flexible enough to cope with extant inconsistencies. A recently developed cause-based approach provides a uniform foundation of inconsistency tolerance for query answering and integrity checking. It also provides flexibility to handle different degrees of inconsistency. We improve the cause-based approach by focusing on causes that are basic, i.e., irreducible to other causes.
