SQL Projects For Data Analysis In 2024: Examples

Here are some best real world SQL projects for data analysis that can help you out when it comes to the data analysis aspect:

1. Blood Bank Management System

Blood banks are essentially the direct source of a deluge of data. It does the monumental task of collecting, preserving, and providing blood to patients in need. The Blood Bank Management System enables the proper maintenance of records pertaining to the availability as well as the quality of blood.

If you are interested in SQL practice projects within the healthcare industry, this project is a valuable opportunity to explore real world SQL projects for data analysis.

Create an elaborate blood donation database that includes the following details:

• Donors: Information such as name, age, blood group, and medical history.
• Recipients: Details like name, age, and blood group.
• Hospitals: Records of hospitals that request blood from the blood bank.
• Blood quality: Status of the blood, including whether it is contaminated.

SQL data analysis project idea

Use the dataset to answer key questions, such as the following:

• • Is there a sufficient supply of blood available at the blood bank?
• • Does any donor have blood-borne diseases?

This project will help you get the right practical experience in SQL and data analysis within a real-world healthcare context.
