MiniOB is a compact, educational relational database developed by the OceanBase team for learning database internals from scratch. It includes simplified implementations of SQL parsing, query optimization, execution, storage engine, B+ tree indexes, MVCC transactions, and redo logging, paired with progressive exercises and tutorials.
Use cases
- learn how a database kernel works
- practice implementing database internals step by step
- prepare for the OceanBase database competition
- study SQL parsing and query execution
- understand B+ tree indexing and MVCC transactions
- build engineering skills in memory management, networking, and disk I/O
When to choose
- you want a beginner-friendly codebase to learn database internals
- you are a student training for database competitions or interviews
- you want guided exercises with tutorials and documentation
When to avoid
- you need a production database with security, concurrency, and full transaction guarantees
- you need a fully-featured SQL engine for real workloads
