Joiner will join the two different data sources based on a
join condition ,and pass only the rows which satisfy that
condition.discards the remaining rows.
Joiner transformation supports 4 types of joins at
Informatica level
Normal
Master Outer
Detail Outer
Full Outer
LookUp Transformation
Lookup transformation basically for Reference,based on the
lookup condition.when u want some data based on target
data ,will take lookup on that particular table and
retrieve the corresponding fields from that table.
we can override the lookup transformation using the SQL
query.
