My very first exercises in SQL

Learning SQL and Tableau for Data Analysis

Starting a bootcamp is exciting! The very first project we did in the Data Science bootcamp at WBS Coding school is all about learning SQL and using it to analyse a given data set. The following scripts, charts, and presentation were created in the first 2 weeks of the bootcamp.

Important

The topic of the project was: should a Eniac, a well established European company that sells high-end apple products and product accessories, use the warehouse and delivery services of a big Brazilian company called Magist to expand into the Brazilian market. The fictitious scenario takes place in 2018, long before Covid and AI-Chat bots. The goal is: explore the data and come to a conclusion whether Magist is a good fit for Eniac's expansion into Brazil.

Programmes used

I learned to make queries in MySQL Workbench, create charts in Tableau based on the insights I gained from my queries, and finally got to work on and present the results with my teammate to the rest of the group in a Canva presentation.

Tasks to accomplish

  • learn about SQL and its functions
  • install and get familiar with MySQL Workbench
  • try first queries and look through data
  • start the analysis by answering business questions about our fictitious use case
  • gather the insights from the different queries and visualise it using Tableau
  • do not start hating Tableau because it has almost too many options
  • prepare and practice a presentation with your charts and arguments in Canva
