What is the difference between source qualifier and normalizer in Informatica?

Question

Suppose we have a Source Qualifier transformation that populates two target tables. How do we ensure TGT2 is loaded after TGT1?

Answer 1

1. SQ is used to represent the data from sources (relational, flat file) which Integration service can read

2. Normalizer is used as a source qualifier when we have Cobol source (Denormalized), which SQ can not read

3. Normalizer can be used for transposing columns into rows
