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 a numerical correlation analysis to compute the age average of the personnel of different enterprises located in different states. Three database columns are used for the analysis: STATE, AGE and COMPANY.
About this task
Note: The numerical correlation analysis is possible only on database columns for the time being. You can not use this analysis on file connections.
