In performance testing, correlation is a technique used to capture dynamic values for scripts that are recorded with a load test software program.
For example, an unmodified script may contain a hard coded session identification number which was sent to the client during the time the script was recorded. If this script is played back without correlation, the script will most likely fail, since the session ID may no longer be valid. By using correlation, dynamic values passed from the server to the client can be captured during replay and then incorporated into the script where they are needed.

Data Correlation
(AKA: Input Data Correlation, Dynamic Data Capture)
In performance testing, correlation is a technique used to capture dynamic values for scripts that are recorded with a load test software program. For example, an unmodified script may contain a hard coded session identification number which was sent to the client during the time the script was recorded. If this script is played
back without correlation, the script will most likely fail, since the session ID may no longer be valid. By using correlation, dynamic values passed from the server to the client can be captured during replay and then incorporated into the script where they are needed.
There are different ways to correlate, depending on what load test software program is under use. Typically, correlation is done by either manual coding in the script, or by using a correlation feature of the load test software program.
