Cognos and Informatica are different tools and don't do the same thing.

Informatica is a ETL tool.  It extracts data from various sources (Oracle, db2,
Sybase, etc) transforms it and loads data into the warehouse to prepare data for Cognos reporting.

Cognos is a BI reporting tool that produces list/crosstab/graphic reports mainly for analysis.  It uses data from data warehouse that's ETL'ed by informatica or other ETL tools for better performance.
Cognos is is kinda similar to Business Objects, Crystal reporting.
