Almost everyone knows that these are the tools a Data Analyst works with:
➡️ SQL
➡️ Excel
➡️ Power BI/Tableau
➡️ Python
But people getting started with analytics are confused about the preferences of picking these tools.
There are various kinds of data analytics roles available in the market :
➡️ BI + SQL: Will primarily be involved in BI development.
➡️ SQL + Excel: Will primarily work on Excel reporting.
➡️ SQL + Python: Will primarily do data analysis using python.
Now, If you are getting started with learning analytics, choose any one role that interests you the most and focus on completing the primary tools that the role requires. Learn them VERY WELL.
Learn any of the above combinations that interests you first and then start looking out for opportunities which ask for these primary tools and simultaneously start learning the basics of the 3rd tool.
You don't have to focus on being good with each and every tool but being good with any of the above combinations always works.
