Coursework and personal projects using SQL.

Amy Brown's SQL Portfolio

Hello, and thanks for stopping by! This repository contains examples of SQL I've written for solo projects and while working through SQL, machine learning, and other data analytics courses. Below are a few highlighted projects, including data visualizations I created using Tableau. Feel free to take a look around and reach out if you have any feedback or questions.

Highlighted Projects

  • Spotify Top Songs Analaysis - SQL: In this project, I used a dataset found on Kaggle to analyze trends in the top 50 songs of 2021. Using pitch-class integer notation, I examined the key and tonality for these top songs. I joined data from a Hooktheory database to compare the most popular song keys with the song keys most represented in the top 50 Spotify tracks of 2021.
  • Predictive Book Ratings Analysis - SQL: In this project, I used my own data from Goodreads to analyze how my book ratings differ from the average ratings found on Goodreads. I categorized the books by genre and obtained the average difference in rating per genre. I created another table containing similar data for books that won the Booker Prize for Fiction from 2000-2021 and joined this data to predict, for each Booker Prize-winning book, what my rating would be.

Superstore Profit Dashboard - Tableau

  • Data: Tableau sample data
  • Audience: Sales executives
  • Purpose: Identify factors behind low profit ratio in order to boost profits

In this dashboard, I used a Tableau dataset containing sample sales data from 2018 to 2021. Though the sample dataset provides a wider overview of sales data, I saw an opportunity to strategically visualize clear, actionable insights to my fictional audience of sales executives. The dashboard allows my audience to immediately pinpoint the geographical, categorical, and seasonal factors that are leading to profit loss — providing the guided insight that allows them to impact change on their team.

World Happiness Rankings Dashboard - Tableau

  • Data: World Happiness Report
  • Audience: Anyone interested in geography & culture
  • Purpose: Explore and interact with visualized world happiness data

The World Happiness Report dataset ranks the happiness of 155 countries from 2015 to 2019. For this dashboard, I wanted the audience to be able to dive deeper into countries around the world and gain a contextual understanding of where those countries rank against the world average. The dashboard allows the user to explore the world map and compare metrics across countries. I'm endlessly interested in world geography and cultural nuances, so I created a dashboard that gets right to the information points I would most want to play with.
