Google data analytics is a well-made certification where you’ll learn:

• What does it mean to be a business analyst (BA)
• What are the tools and skillset that you might need if you want to pursue a career as a BA

Overall it’s a good course with great material, food for thought about BA, and a good introduction to the BA tools (Tableau, Excel, SQL, R…). For my taste and current experience, it’s was a bit too qualitative.
