US Patent 8082243 Semantic discovery and mapping between data sources

In one aspect, semantics and relationships and mappings are identified between a first and a second data source. Data between the first and second data source is compared. A binding condition is discovered between portions of data in the first and the second data source based upon the comparison, wherein the binding condition identifies data within the first and second data sources that map to each other. The binding condition is used to discover correlations between portions of data in the first and the second data source, wherein the correlations identify data in the first data source that correspond to values in the second data source. The binding condition and the correlations are used to discover a transformation function between portions of data in the first and the second data source, wherein the transformation function generates data in the second data source data in the first data source.
