What are the concepts and theories that I should learn if I want to become a data analyst? I already know what I should learn for the technical skills (excel, sql, python, bi tools), but I'm confused on what other theories and concepts (business/data-related) that I should learn?

After doing some research on google, I found out that there a lot of different types of sql (eg: mysql, postgresql, T-sql, etc). My question is, which type of sql should I learn and master if I want to become a data analyst?
