Design and Development

Talend Studio provides the possibility to explore relationships and correlations between two or more columns so that these relationships and correlations give a new interpretation of the data through describing how data values are correlated at different positions.

Note: Column correlation analyses are possible only on database columns for the time being. You can not use these analyses on file connections.

It is very important to make the distinction between column correlation analyses and all other types of data quality analyses. Column correlation analyses are usually used to explore relationships and correlations in data and not to provide statistics about the quality of data.

Several types of column correlation analysis are possible. For more information, see Creating a numerical correlation analysis, Creating a time correlation analysis and Creating a nominal correlation analysis.

For more information about the use of data mining types in Talend Studio, see Data mining types.
