Best SQL Projects For Beginners

Here are a few SQL projects that can be considered as good starting points for beginners :

1. Simple data analysis: 

Use SQL to extract and analyze data from a simple database, like a CSV file containing sales data. Try to answer questions like, "What are the top selling products?" and "Which month had the most sales?"

2. Movie database: 

Create a database of movie information (title, director, year, etc.) and write SQL queries to answer questions like, "What are the top 10 movies of all time?" and "Who are the most successful directors?"

3. Inventory management: 

Create a database to track a simple inventory system for a small store. Write SQL queries to answer questions like, "What are the most popular items?" and "When do we need to reorder a particular product?"

4. Employee database: 

Create a database to track information about employees (name, job title, salary, etc.) and write SQL queries to answer questions like, "What is the average salary of employees in the company?" and "Which job titles have the highest salaries?"

5. Bank transactions:

Create a database to store information about bank transactions (date, description, amount, etc.) and write SQL queries to answer questions like, "What is the total balance for a given period?" and "How much money was spent on groceries in the last month?"

6. Music library:

Create a database to store information about your music library (artist, album, year, etc.) and write SQL queries to answer questions like, "What is the most popular music genre?" and "Which artists have the most albums?"

7. Social network:

Create a database to store information about a simple social network (user, friend, message, etc.) and write SQL queries to answer questions like, "Who are the most popular users?" and "Who is the most connected user?"

8. Book library:

Create a database to store information about a book library (title, author, ISBN, etc.) and write SQL queries to answer questions like, "What are the top 10 most popular books?" and "Which authors have the most books in the library?"

9. Online store:

Create a database to store information about products, customers, and orders for an online store. Write SQL queries to answer questions like, "What are the best-selling products?" and "Which customers have placed the most orders?"

10. Hospital database:

Create a database to store information about patients, doctors, and treatments in a hospital. Write SQL queries to answer questions like, "What is the average treatment time for a given condition?" and "Which doctors have the most experience in a particular specialty?"

11. Weather data:

Obtain weather data from a public API and store it in a database. Write SQL queries to answer questions like, "What is the average temperature for a given location?" and "What is the total rainfall for a given period?"

12. Sports statistics:

Obtain sports statistics from a public API and store it in a database. Write SQL queries to answer questions like, "What is the average score for a given team?" and "Who are the top 10 players with the most goals?"

These projects can be a great way to gain hands-on experience with SQL and develop a deeper understanding of how to use the language to solve real-world problems. These projects can be implemented using any relational database management system, such as MySQL, SQLite, or PostgreSQL.
