Camila Henrique explains the importance of knowing SQL:
I wanted to talk about this because I see a lot of doubts and lack of direction from people who are either beginning now in IT land or thinking about switching careers. The short answer to “do I need to know SQL for a data job?” , is yes. In the next few paragraphs I explain why I think so.
It’s easy to get caught up in all the fancy programming languages and methodologies for projects that sometimes the basics… are just not there. I believe having a good foundation opens paths to other doors that you could not see before. And I’m certain that SQL is one hell of a foundation to have in the data land.
This is also a good time to slip in a reminder of Feasel’s Law.
