Abstract: As more information becomes available, the ability to quickly incorporate new and diverse data sources into existing database systems becomes critical. Schema coercion addresses this need by defining the mapping between databases as a collection of mappings between corresponding constructs. This work defines a comprehensive schema coercion tool: it transforms schemata into corresponding ER representations, identifies correspondences between them, and uses these correspondences to generate a...
