What are column correlation analyses?

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.

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.

This is why it is not possible to generate reports from column correlation analyses because reports are usually used to determine the improvement or degradation 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.
