im new to the software industry and have been trained in data warehousing technology. Presently im working on DTS and Cognos as the ETL and Reporting tools respectively. During my training i was told that Oracle certifications are beneficial in this field and decided to do it. But i found out that there are two streams in it one for developer and the other for database administrator. im confused which one to take. if you could help in deciding for the same it would be helpful.
