23rd-February-2019: SQL & Python tutorials
I found two tutorials that seem very useful.
- SQL Tutorial: Seems to cover from Basic to Advanced skills in SQL while using the host's editor, but the skills that you'll learn are likely general enough that they're transferable to other editors. Recommended highly on HN.
- Python Tutorial: "Learn Python for business analysis using real-world data." Seems to set an analyst on a good path for using Python for data analysis. They link to additional resources for further growth.
