RDBMS Playground Lazy Evaluation Ltd

RDBMS Playground is a cross-platform terminal application designed to teach relational database concepts in a safe, interactive environment. It helps users learn tables, columns, primary and foreign keys, relationships, indexes, queries, and query plans through guided, keyword-based commands (simple mode) and raw SQL (advanced mode). Built for education, it bridges the gap from basic database concepts to real-world SQL execution.

Key Features:

• Interactive Learning Modes: Start with simple, keyword-based commands in "beginner mode" or switch to advanced mode for raw SQL as you progress.
• SQL Transparency: Execute simple-mode commands and see the equivalent SQL code, making the transition from concepts to real queries seamless.
• Undo and History: Experiment freely without fear of losing work; every change is reversible, and your session history is preserved.
• Query Plan Visualization: Analyze how queries are executed by viewing detailed query plans, helping you understand indexes, scans, and optimization strategies.
• Assistive Editor: Get real-time command suggestions, syntax highlighting, error detection, and hints as you type for a smoother learning experience.
