Data
driven is the
property by which the Informatica Server decides the way the data needs to be
treated whenever a mapping contains Update Strategy Transformation.
For
example Whenever we use Update Strategy Transformation we need to mention
whether its DD_UPDATE or DD_INSERT or DD_DELETE in the mapping.One
mapping may contain two or more Update Strategy Transformation. Therefore, in
order for the session to get executed successfully mention Data Driven
property in the session properties for that particular mapping.
For
DD_UPDATE records needs to be updated
DD_INSERT records needs to be newly
inserted.
DD_DELETE records needs to be deleted
Very nice short and clean explanation.
