SQL Foundations: Optimizing Databases with Indexes, Views, and Sequences

As database sizes grow, basic queries can become slow and complex to write. Understanding how to structure and optimize database objects is the key to managing data efficiently. This course helps you transition from basic SQL queries to professional-grade database management, showing you how to accelerate data retrieval, simplify data access layers, and manage auto-incrementing values securely. What you'll learn: - Understand the fundamental mechanics of database indexes and how they speed up search operations. - Create and manage database views to simplify complex queries and secure sensitive data. - Implement sequences and auto-incrementing generators to handle unique identifiers reliably. - Analyze query execution paths to determine when and where to apply indexes. - Apply modern SQL best practices, including when to use Common Table Expressions (CTEs) versus traditional views. - Practice writing optimized SQL code through step-by-step written exercises and logical database design scenarios. You will begin with foundational definitions of database objects before moving into the practical syntax for creating, modifying, and dropping indexes, views, and sequences. The course guides you through structured text explanations, clear code blocks, and logical troubleshooting scenarios. This course is designed for beginner to intermediate database users who want to step beyond basic SELECT statements. No advanced database administration experience is required.
