INTERVIEW QUESTIONS DATA WAREHOUSING INFORMATICA DETAILS

Question: Can any one explain real time complain mappings or complex transformations in Informatica.
Specially in Sales Domain.

Answer: Most complex logic we use is denormalization. We dont have any Denormalizer transformation in INformatica. So we will have to use an aggregator followed by an expression. Apart from this, we use most of the complexicity in expression transformation involving lot of nested IIF's and Decode statements...another one is the union tranformation and joiner.
