Automatic correlation from web point of view, can be set in
recording options and correlation tab. Here we can enable
correlation for the entire script and choose either issue
online messages or offline actions, where we can define
rules for that correlation.  Automatic correlation for
database, can be done using show output window and scan for
correlation and picking the correlate query tab and choose
which query value we want to correlate. If we know the
specific value to be correlated, we just do create
correlation for the value and specify how the value to be
created.

view.We have to give the left boundary and right boundary 
for it
