Relatively new to Qlik space and exploring options. I'm need an option to query big datasets for which qvds cannot handle (or less performant). I can display high level info but when user clicks on a specific data point, want to provide raw data specific to that data point. The underlying data is in TBs and its like finding needle in haystack. What's the best approach? ODAG or Dynamic views. I know it can be done via cognos which can dynamically issue queries to database based on user request.
