By Leon Amsel

Practical SQL and PostgreSQL for Developers
Learn Real-World Query Skills, Performance Tuning, and Modern Postgres Tools to Deliver Efficient, High-Quality Apps
What separates average applications from fast, reliable, production-grade systems? Almost always, it comes down to one thing: how well developers understand and use their database. If you've ever wondered why a query slows down under real traffic, why an index suddenly matters, or how to shape data so your app remains stable as it grows, this book is built for you.
Practical SQL and PostgreSQL for Developers gives you the modern, hands-on guidance needed to build applications that stay fast, predictable, and easy to maintain. Instead of abstract theory, you'll work with real SQL patterns, real PostgreSQL features, and real performance techniques used in production systems today. Whether you're building SaaS platforms, analytics workloads, or everyday backend services, this book shows you how to think and build like a database-first developer.
You'll learn how SQL and PostgreSQL actually behave under real workloads, and how to use that knowledge to write cleaner queries, structure better schemas, and tune your database with confidence. You'll understand not just what to write, but why it performs the way it does.
By the time you finish, you'll be able to: Write efficient SQL queries built for real application needs.Design schemas that scale predictably as your data grows.Use PostgreSQL indexing, constraints, and data types to improve performance.Analyze slow queries with EXPLAIN and fix them using proven tuning techniques.Work confidently with JSONB, CTEs, window functions, triggers, and advanced SQL features.Set up PostgreSQL environments, replication, pooling, and configurations with developer clarity.Deploy and monitor Postgres-backed applications using industry-standard tools.Apply practical techniques for concurrency, reliability, backups, and version upgrades.This book is written for developers who want to strengthen their SQL fundamentals and use PostgreSQL as more than a simple storage layer. The explanations are clear, the examples are practical, and the methods reflect how real teams build high-performance systems.
If you're ready to write faster queries, build smarter database structures, and ship applications that perform well in production, then now is the time to take the next step. Start reading and level up your PostgreSQL skills today.
