This project was developed as part of a college assignment and focuses on creating two main queries within the context of a Nutrition Store example.

The queries are as follows:

1. Identify the best-selling imported creatine brand and the best-selling domestically produced whey powder brand between 2015 and 2020, along with their respective total incomes.
2. Determine the ratio of females to males among users who have ordered L-karnitin at least 5 times in the last 5 years.

In addition to the SQL query codes, the project includes:

• Java application code
• UML class diagram
• Flowchart
• Explanation of the project's main idea
