If they have already defined at databse level,then what is
the necessity of maintain the primary-foreign key
relationship at Informatica level.You just import those
tables from the database and load the data by developing
the mapping.but enable the option "constraint based load
ordering"in session config objects before you are going to
run the session. why because
informatica server(Integration Service) doesn't know the
relatioship between the target tables which you are going
to load eventhough they have already defined at databse
level.So you should use the option "Constarint Based load
ordering".
Then only Informatica server will check relationship
between the those tables and first it will load data in the
parent table(which has Primary key) and then child table
(which has foreign key)

to improve the performance of aggregator we use sorted input option and use sorter t/r befor aggregator. But here we are increasing one more cache in our mapping i.e; sorter. So how can u convince that you are increasing the performance.?

I've a denormalized table EMP(empno,ename,phone,addr1,addr2,fax,email). Now I want to insert the record into target in the format that, there will be 2 target rows for 1 source record. In target the row needs to be inserted as: ROW1: empno,ename,addr1,phone ROW2: empno,ename,addr2,fax,email And I'm not allowed to normalize transformation. How to achieve?
