This module teaches students how to organize and refine data retrieval using SQL. It covers the use of the ORDER BY clause to sort results based on one or more columns, as well as filtering techniques with DISTINCT, LIMIT, and OFFSET to manage query output. Students will learn how to enhance data readability and control result sets efficiently. Through hands-on practice, learners will develop skills to produce clean, relevant, and well-structured query outputs.
