HI! First of all SAS and QlikView act completely different from each other. SAS is a procedurebased language and have consepts that are spezialized for ETL process and SCD. SAS/DI Studio is very popular part of SAS for doing ETL, but you can use Datastep programming such as Script in QlikView as well. SAS have Enterprise Guide which is a level above datastep and it is more or less used for analyzing data. If you should do a good comparison betwenn the two in the context of ETL you need to compare SAS/DI Studio in SAS with QlikView Expressor, or several other 3rd party systems. About career, i would not hesitate to go for QlikView. QlikView is the best system ever and when you are in the other end of your dataprosessing, SAS generate PDF docs in WEB and QlikView generate a world of possibilities with the fantastic green, white and gray.
