The Transformation which Converts the source(relational or
flat) datatype to Informatica datatype.
So it works as an intemediator between and source and
informatica server.

Tasks performed by qualifier transformation:-
1. Join data originating from the same source database.
2. Filter records when the Informatica Server reads source
data.
3. Specify an outer join rather than the default inner join.
4. Specify sorted ports.
5. Select only distinct values from the source.
6. Create a custom query to issue a special SELECT
statement for the Informatica Server to read source data.

Answer / fatima

source qualifier is also a table, it acts as a
intermediator between source and target metadata and, it
also generates sql, which creating mapping in between
soucre and target metadata.

Answer / kumar

Flat files or XML files into a unique readable format.

Answer / sandeepbabu

Represents the source record set queried by the integration server/service.It is mandatory in the mapping when the source is relational or flat files.And it is a Active transformation.
source qualifier contain some properties is given bellow:
1>Sql query:It is generated by integration server by default and It contain Sql override,used to modify the default select Statmets...
2>user defined join:It is content of WHERE Clause to join separate Source
3>source filter:Filter applied to source Records..
4>Number of sorted ports:used to sort input ports.When we are using sorted ports the Powercenter add ports by default'Orderby'.BY default sorted ports are Zero
5>Select Distinct:selct unique values only
6>pre sql:The sql database before reads the source data
7>post sql:The sql database after write the data in to target table..

Answer / pradeep

using sq'transformation we can driveout data from an
object,and it can drivein to the next transformation,this
is an mediator betwwen source object and to the next
transformation to get the data fom source object.
