LearnDB is an educational project that teaches database internals by guiding users through implementing a simplified SQLite-like relational database from scratch in pure Python. It includes a working RDBMS with a custom SQL lexer/parser, on-disk B-tree storage, and a REPL, but is explicitly not suitable for production storage.

Use cases

• learn how databases work internally
• implement a relational database from scratch
• study btree storage engine implementation
• understand sql parsing and lexing
• tinker with a simple rdbms codebase
• follow a database internals tutorial

When to choose

• you want to learn database internals by reading and modifying real code
• you prefer a simple, pure-Python codebase with zero configuration
• you want a guided tutorial plus reference docs for building an RDBMS

When to avoid

• you need a production-ready database for storing real data
• you need full SQL support like wildcard selects or IEEE754 float arithmetic
• you need Windows support since it relies on fcntl
