1. A method for determining a mapping between a plurality of columns of a first data source and a second data source by using a fuzzy match, the method comprising: identifying a join condition between the plurality of columns of the first data source and the second data source; constructing source data objects based on a set of relationships between the plurality of columns of the first data source and the second data source and the identified join condition; determining a fuzzy match between the plurality of columns of the first data source and the second data; identifying the mapping corresponding to the fuzzy match between the plurality of columns of the first data source and the second data source; and generating a window providing a display of success for the mapping between the columns of the first data source and the second data source.
