Learn SQL
Learn-SQL is an interactive platform and exercise repository designed for beginner programming education, specifically focusing on SQL query practice and relational database management. It functions as an in-browser learning tool where users can execute database scripts and practice foundational querying skills without requiring any backend server infrastructure.
The platform evaluates database queries directly inside the browser session by compiling an entire SQL engine into portable WebAssembly bytecode. Curriculum content, lesson instructions, and challenge prompts are stored as plain text markdown files that are parsed dynamically for user interface rendering. Additionally, the application initializes database environments at runtime by parsing static SQL script files, while structuring its practice problems and curriculum content into hierarchical folders that map to the application navigation structure.
