BusTub is an educational relational database management system written in C++ and built at Carnegie Mellon University for the 15-445/645 Introduction to Database Systems course. Students implement its core components (storage, indexes, query execution, concurrency control) through course projects, and it supports basic SQL with an interactive shell.

Use cases

• learn how a relational database management system works internally
• implement a buffer pool manager and disk storage for a DBMS
• build B+ tree and hash table indexes from scratch
• implement query execution operators like joins, sorting, and aggregation
• study concurrency control and transaction processing in a real codebase
• practice systems programming in C++ on a database codebase

When to choose

• you are taking or self-studying CMU 15-445/645 and want to complete its projects
• you want a guided, hands-on way to learn DBMS internals
• you want a small, readable C++ codebase to explore database architecture

When to avoid

• you need a production-ready database for real workloads
• you need full SQL compliance, high performance, or durability guarantees
• you want to deploy a database server in an application
