This project was an analysis on 120 years of Olympic games results (1896 - 2016). The data was sourced from a public site: Data Source. I created a database and tables with PostgreSQL, imported the CSV files, and then performed various queries for analyisis (See Below). Then I developed a Tableau dashboard Linked Here to visualize key metrics:
- Total medals count and percentages per country
- Top winning athletes
- Total medals and corresponding percentages for different age groups
- Distribution of each sport's average height, weight, and age
- Filters for year, sport, country, season and sex
