In informatica level the aggregator transformations output can be obtained by replacing it with the following transformations
1) Sorter transformation -- Used to sort the data asc/dec
2) Expression Transformation -- basic transformation used almost in all the mappings
3) Filter Transformation -- To obtain the records with specific condn.
Aggregator transformation will reduce the number of records by aggregating on some specific columns given by us .
The Reverse transformation of Aggregator is Normalizer Transformation which will increase the number of Records.
