Abstract:

In order to share and integrate information from multiple autonomous and heterogeneous data sources in a reliable environment, we must deal with the schema mapping problem. This problem involves both: a) the mapping of one or more schemata in another one (named the target); and b) the discovery of one or more executable transformations (e.g., SQL queries) that transform the source data into the new structure in the target. In this presentation, we will show some concepts related to schema mapping, and then focus on two schema mapping tools: CLIO and ++SPICY.
