Beginner SQL Projects

Simple data manipulation activities including building simple tables, entering data, and querying data using fundamental SELECT statements are frequently included in beginner-level SQL projects.

Basic data analysis activities like counting, summarizing, and filtering data may also be a part of these initiatives. Lets look at some projects-

#1 Grocery Management System

The grocery management system is a tool that helps store owners and managers keep track of their inventory, sales, and customers.
