Hi all, i am new to this site and new to Informatica too. I
have few questions regarding that.
1) When we load flat files into target tables how do we
identify duplicates? and where do load the duplicate
records for further reference?
2) How do we do chage data capture? Is this Slowly changing
Dimension technique?
Thanks in Advance

From 2nd router Transfromation we have a Separate Target
Table.

chage data capture(CDC) Mean newly Inserts, Updates
Based on Data loading time,,
This Inserts, Updates only Slowly changing Dimension
technique.
