Answer
# 1
Correlation is used to obtain data which are unique for each
run of the script and which are generated by nested queries.
Correlation provides the value to avoid errors arising out
of duplicate values and also optimizing the code (to avoid
nested queries). Automatic correlation is where we set some
rules for correlation. It can be application server
specific. Here values are replaced by data which are created
by these rules. In manual correlation, the value we want to
correlate is scanned and create correlation is used to
correlate.

# 2
Correlation is a method of capturing values in a script as 
a result of dynamic data passed from the server to the 
client and back. the values are saved in the Load runner 
parameter and is reused instead of original recorded value.
