why we use source qualifier transformation?

Question Posted / su

Answer Posted / su

The source qualifier converts user defined data types to
informatica data types.
The sorce qualifier is automatically generated only for the
flat files,for other sources we need to create it.
The basic transformation that is used in informatica is
source qualifier transformation.
We can write sql query in this transformation and we can
even override the existing sql query.
Using this transformation we can even perform
aggregator,filter,expression,sorting and join
transformations also.
It is used to join the homogenous source types.
