About Informatica server process that how it works relates to mapping variables?

By



Informatica primary uses load manager and data transformation manager 
(dtm) to perform extracting, transformation and loading. Load manager reads 
parameters and variables related to session, mapping and server and passes 
the mapping parameters and variable information to the DTM.DTM uses this 
information to perform the data movement from source to target
