Cognos Decision Stream Support for Peoplesoft ERP

[seshu]

Hi

Please clarify whether Cognos Decision Stream supports PeopleSoft Enterprise ERP
I know that it supports Peoplesoft EPM but I am not sure about the earlier versions

Also,

Which of the below strategies would be a better option


1) Using Informatica (Power Connect for Peoplesoft) for ETL and then use Informatica Power Analyzer or Cognos Tools for OLAP
2) Using CognosÃ,  Decision Stream for ETL from PeopleSoft and Cognos OLAP tools for Analysis and Reporting

Thanks
