Abstract
A method and software tool for identifying relationships between columns of one or more data tables are disclosed. In the disclosed method, a relationship indicator is computed for each of a plurality of column pairs, each column pair comprising respective first and second columns selected from the one or more data tables. The relationship indicator comprises a measure of a relationship (e.g. indicating a strength or likelihood of a relationship) between data of the first column and data of the second column. Relationships between columns of the data tables are then identified in dependence on the computed relationship indicators. The identified relationships may be used to create and execute data queries.
