The material introduces SQL concepts and differentiates Data Definition Language (DDL) from Data Manipulation Language (DML), then explains SQL Server setup using SQL Server Management Studio. Subsequent sections cover schema creation with CREATE TABLE, modeling and constraints, and practical data operations: INSERT INTO, UPDATE, DELETE, and SELECT with ORDER BY, DISTINCT, WHERE, operators, wildcards, TOP, aliases, and joins. It also reviews SQL scripts, comments, variables, global variables, and flow control using
