## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: orm, database-driver, serialization
- domain: databases, backend, developer-tools
- platform: windows, cpp, cross-platform
