What is a lookup table?

SCJP 1.5/1.6 Exam Kit

!!!Answer!!!- From Technical Expert


The lookup table can be a single table, or we can join multiple tables in the same database using a lookup query override. The Informatica Server queries the lookup table or an in-memory cache of the table for all incoming rows into the Lookup transformation.

If your mapping includes heterogeneous joins, we can use any of the mapping sources or mapping targets as the lookup table.
