Though I'm not moving to Qlik but has read about comparisons between top few analytics tools including Qlik, Power BI, Tableau, QS etc.
Out of all, QlikView is highly adaptable and provides wide-ranging deep analytics. It also has integrations to Deltek products, so if you use Deltek for time & expense or earned value management (EVM) reporting, QlikView is a natural choice. Overall, QlikView also continues to have one of the industry’s highest customer satisfaction ratings.
On the other hand, Microsoft’s Power BI is inexpensive and plugs-in seamlessly with MS Office. It is a solid option if you need quick access to specific analytics or intensive reporting (and have personnel who are skilled in MS-based data queries). In the long run it may challenge QlikView, Tableau or other analytics tools. Microsoft Power BI is the only one of these three data visualization and analytics apps that have extensive R and big data-related integrations, ensuring this specific apps’ scalability for larger projects.
I don't think old are really eating the young. To me, this intergenerational conflict is exaggerated. As technology improves and so is human life span, we all have to face this when we become old.
This will clearly shift a considerable measure from nation to nation, however the essential thought is that you can't make a correct clone, yet you can make a knock-off rendition.
