As a business analyst, I'm wondering is it important and useful to get a qlik sense certification? I know there are 3 kinds of certifications: Business Analyst, data Architect, Developer, and also certifications from Udemy, etc. Which would be the best one for a business analyst career path?
I would say Data Architect as this is what brings value. It (almost) never happens that you get perfect data in one table. In most cases you will have to understand and clean your data, prepare the data model, do some calculations, etc. Doing all this in the data load script (Data Architect) provides much more flexibility.
A Business Analyst needs a Data Architect who prepares the data. A Data Architect, however, has enough knowledge to do what a Business Analyst does. Also look here at the domain areas to see what is covered by the exams: Qlik Sense Certifications
