Both are different products. Qlik Sense is not yet fully geared up. Knowing qlikview would be a better option I feel as of now. Knowing qlikview would always keep you open to migrate to qlik sense very easily. So, qlikview(at least for these two-three months).
Thanx. Can you tell me any website where i can explore more about qlikview. I mean i have problem making complex expressions and also understanding them. So how can i explore more about making complex expressions ??
