ormpp is a modern C++17 header-only ORM library that provides a unified API for MySQL, PostgreSQL, and SQLite. It uses compile-time reflection to map C++ structs to database tables, with type-safe chained query building, connection pooling, and async MySQL support.

Use cases

• map C++ structs to database tables without writing SQL boilerplate
• switch between mysql, postgresql, and sqlite with a unified API
• build type-safe SQL queries with chained calls
• pool database connections with health checks
• run async non-blocking MySQL queries
• encrypt SQLite databases with SQLCipher

When to choose

• you want a header-only C++ ORM with no build step
• you need to support multiple databases behind one interface
• you prefer compile-time reflection over runtime ORM overhead
• you want type-safe query construction checked at compile time

When to avoid

• you need databases other than mysql, postgresql, or sqlite
• you need a mature ORM with extensive tooling and migrations like heavier frameworks
• your project cannot use C++17 or newer compilers
