This is a position that not only requires understanding on database management and organization, but also soft skills such as great communication skills in the given language, as well as some presentational skills.
There are several courses on our platform that can help you prepare for such a position. Among others, I'd say the most relevant are the ones related to Excel, SQL, and data visualization. Here are the links to these courses for your convenience:
