SQL Fundamentals (NCLab): This online, self-paced, learn-by-doing course provides a comprehensive, hands-on introduction to relational databases and Structured Query Language (SQL). Learners explore key database concepts, including the structure and purpose of data, relational vs. non-relational databases, referential integrity, the ACID principles, and SQL syntax across different database systems. Using PostgreSQL, students write real SQL queries to retrieve, filter, group, and summarize data with commands like SELECT, WHERE, GROUP BY, and HAVING. They gain experience working with multiple tables, modifying table structures, and joining datasets using inner joins. The course also covers constraints, default values, and table management techniques. Through engaging, real-world practice using sample databases like Northwind and World, learners build essential skills for careers in data analytics, software development, and information systems.
