• It is the logic to Informatica to transform the data according to the business needs.

Types of Transformations

Transformations are basically of two types:

• Active

Active Transformation:

A transformation is called as an active transformation if it allows change in the record count.

e.g. If there are 20 records coming from the source but only 5 are sent to the target after transformation.

Passive Transformation:

A transformation is called as a passive transformation if it does not allow any change in the record count.

e.g. If there are 20 records coming from the source and all 20 are sent to the target after transformation.
