I just recently switched companies and at my new company, they try to solve almost everything with Qlik Apps, but in all my classes and/or certificate programs I was taught that the front end tool should be ‘dumb’. The data logic should be in the data warehouse. The consultants for Qlik think otherwise and try to transform in qvd. What is the best practice in your company?</P> </DIV> </DIV> Wed, 01 Dec 2021 10:14:40 GMT https://community.qlik.com/t5/Connectivity-Data-Prep/Best-practices-data-warehouse-Qlik/m-p/1865366#M9922 maniqwils 2021-12-01T10:14:40Z https://community.qlik.com/t5/Connectivity-Data-Prep/Best-practices-data-warehouse-Qlik/m-p/1866084#M9930 <P>It must not be black or white else it could be each shade of grey.
