## Description

Want to learn SQL but tired of theoretical tutorials? SQL Gym lets you practice from the very first minute.<br><br>Write real queries against a fictitious store database (customers, products, and orders) and receive immediate validation. No servers, no registration, no internet connection.<br><br>How it works<br><br>You progress through a structured learning path in 5 modules:<br><br>• SELECT — retrieves the data you need<br>• WHERE — filters rows with conditions<br>• ORDER BY — sorts your results<br>• GROUP BY — aggregates and summarizes data<br>• JOIN — combines information from multiple tables<br><br>Each exercise presents you with a real business problem: &quot;What are the 5 best-selling products?&quot; or &quot;Which customers have placed more than 3 orders?&quot; You write the query, the app executes it and tells you if it&#39;s correct by comparing the results — not the syntax.<br><br>Key Features<br><br>✓ 20 progressive exercises, organized by concept<br>✓ Results-based validation: any equivalent query is accepted<br>✓ Sandbox mode for free database exploration<br>✓ Integrated schema explorer: query tables and columns at any time<br>✓ Progression system with gradual exercise unlocking<br>✓ Works 100% offline — everything runs on your device<br>✓ No account, no subscription, no ads<br><br>Who is it for?<br><br>For students learning SQL, developers who want to review concepts, and anyone who prefers learning by doing rather than just reading.<br><br>All data stays on your device. The app does not transmit any information to external servers.
