About This League

This league introduces students to MySQL, a powerful open-source relational database management system essential for backend development. You will learn to design, build, and manage databases effectively. This comprehensive guide prepares you for placement interviews and real-world application development.

What you will learn

Upon completion, you will be able to:

  • Create and manage relational databases with precise data types and constraints using MySQL.
  • Write complex SQL queries to retrieve, filter, and sort data efficiently from multiple tables.
  • Implement robust data manipulation techniques for inserting, updating, and deleting records.
  • Utilize aggregate functions and subqueries for advanced data analysis and reporting.
  • Leverage built-in string and date/time functions for data formatting and manipulation.
  • Understand and apply various JOIN operations to combine data from related tables.

What this league covers

ModuleWhat it covers
Module 1: Getting Started with MySQLInstalling MySQL, connecting to the server, and executing basic SQL commands like SHOW DATABASES and creating your first database.
