About this app

SQL Academy teaches you SQL from beginner to expert by running real, not simulated, queries. Every example and exercise runs against practice databases on your own device—no internet connection, no account, no ads.

━━━ LEARN. PRACTICE. MASTER SQL. ━━━

📚 18 modules, 54 lessons—from your first SELECT query to triggers, ACID transactions, window functions, and advanced indexes, organized into 4 levels: Basic, Intermediate, Advanced, and Expert.

💻 Real SQL Editor—each lesson includes an editor where you write and run real SQL against a sample database (store, company, school, e-commerce). Syntax errors are real SQL errors, not a generic message.

🧪 Free Practice—choose any sample database, query its schema, and write your own queries without restrictions, anytime.

❓ Module Quizzes — Multiple-choice questions with immediate feedback to reinforce each topic before moving on.

🏆 Progress and Achievements — Study streak, percentage completed per level, and achievements that unlock as you progress.

🎓 Certificate — Generate a PDF certificate upon completion of your journey, including your name and date.

📖 Glossary — SQL and database terms explained in Spanish, with a search function.

🌓 Dark Mode — Comfortable interface for day or night.
