Through clear written explanations and code-based examples, you will learn to communicate effectively with relational databases. What you'll learn: - Understand core database concepts and the role of the SELECT statement in data retrieval - Filter and sort datasets using logical operators and conditional expressions to isolate key information - Perform data aggregation to summarize large volumes of records into meaningful insights - Apply joins to combine data from multiple tables and create comprehensive datasets - Practice modern techniques like Common Table Expressions (CTEs) for cleaner and more readable code - Clean and transform raw data using built-in SQL functions for analysis-ready results The material begins with essential terminology and the anatomy of a query before moving into practical logic, data manipulation, and multi-table operations.
