Discussion board where members can learn more about Qlik Sense App Development and Usage.
Can anyone guide me in Qlik sense Data Architect Certification ?
can anyone provide some study material ?
You can find recommended materials on the Qlik Sense Certification page: Qlik Sense Data Visualization Certification.
Looking at the Exam Domain Areas I'd say that for the most part you can use (or reuse) the resources for Qlikview.
There are plenty of good books out there. Qlikview 11 for Developers and Qlikview Your Business are two of the best resources.
