A database connection is created in the Profiling perspective of Talend Studio. For further information, see Connecting to a database.
Before you begin
In the example below, you want to create nominal correlation analysis to compute the minimal and maximal birth dates for each listed country in the selected nominal column. Two columns are used for the analysis: birthdate and country.
About this task
Note: The nominal correlation analysis is possible only on database columns for the time being. You can not use this analysis on file connections.
