Projects & Challenges

This MySQL project is a replicated version of the Instagram database, specifically created for conducting data analysis on real-world business inquiries and scenarios. This includes the following:

  • Identifying an appropriate rewards system for loyal users.
  • Launching targeted campaigns to attract users during weekdays with the highest registration rates.
  • Developing strategies to encourage inactive users to resume system usage.
  • And other related business-oriented inquiries.

In this project, I analyzed the world population data using the dataset from CIA World Factbook. The dataset consists of 17 columns and 234 rows, with variables such as Country_id, Country_Territory, Capital, Continent, Population_2022 to 1970, Area, Density, Growth_Rate and World_Population_Percentage. I used SQL in MySQL Workbench to answer analytical questions such as:

  • Which countries have the highest and lowest population densities?
  • Which country has the current highest population?
  • Which country is witnessing the highest population growth?
  • What is the total population number by Continents?
  • What is the density number by Continents?
  • Which countries have experienced the fastest population growth over the years?
  • How has the world population changed over time?
  • In percentage, how much has the total population increased since 1970? and by Continent?
  • Is there a country with a negative birth rate?
  • How many people are there per square km on each continent?

This project not only helped me to gain hands-on experience in SQL, but also provided insights into the world population trends and patterns

MySQL and Python project aims to analyze UK road safety data related to accidents and severity levels. The project includes the following analysis:

  • Identifying the median severity value of accidents caused by various motorcycle types.
  • Analyzing accident severity and total accidents per vehicle type.
  • Determining the average severity by vehicle type.
  • Analyzing average severity and total accidents specifically for motorcycle types.
