Can a data analyst work as a Business Analyst
greetings,
yes. a lot of engineerers take up management jobs. rather maximum number of engineers are offered business related jobs.
if you are a data analyst and want to become a business analyst, then simultaneously study courses from coursera, edx about business analytics.
study financial models also. this knowledge will surely help to take up business related jobs which is more interesting and fun than big data jobs.
hope this helps.
good luck.
