| dc.description.abstract | n this work, we address the schematic discrepancy problem in the integration of ER schemas. Schematic discrepancy occurs when same information is modeled as attribute values, object type (entity type or relationship set) names, or attribute names in different ER schemas of databases. We first define the concepts of local/global attributes and identifiers of entity types and relationship sets resp in an ER schema, which provide essential semantics to resolve schematic discrepancy. Then based on those concepts, we give algorithms to resolve schematic discrepancy among ER schemas to be integrated. | en_US |
