they are 3 different links in the datastage

1.stream link means stright link

2.Reference link it acts like a lookup.

3.Rejected link used in parallel jobs

there 2 types of links in datastage

1 Link partitioner stage

2 Link colector stage

the link partitioner collects the data in single input link & bdiverts to the maximum of 64 output links insert at the same time

link collector stage should collect the data from the passive stage.

if any clarification or any suggetions mail to me.

thanks
