Hi,
Basically Datawarehouse is a concept.To develop DW , we need two tools mainly. One is ETL tool and other one is Reporting tool .
The few famous ETL tools are
Informatica
Data Stage
Few famous Reporting tools are
Crystal Reports
Cognos
Business object
As a DW developer you should aware of atleat one ETL tool and atleat one Reporting tool.The combination is your choice.It better to finout the best combination in point of job market , and then learn them.
Erwin is Datamodel tool. It can aslo be used in DW implementation. You have already have experience on ORacle,So my adivce is go for Data warehousing with oracle or Data warehousing with Informatica .And learn one reporting tool.I donot is there any reporting tool available from ORACLE.
My suggestion on books.
Fundamentals of Datawarehouse by PaulRaj Ponnai and
Datawarehouse toolkit.
http://www.inmoncif.com/about.html is one of the best site for Datawarehouse.
