## What it is
Package ql is a pure Go embedded (S)QL database engine that runs in-process without CGO, originally developed under github.com/cznic/ql. This GitHub repository is now archived and the project has moved to modernc.org/ql, which also ships an accompanying CLI tool for playing with a database.

## Use cases
- embed a sql database in a go application
- pure go sql database without cgo
- lightweight in-process database engine for go programs
- store and query structured data locally with sql
- portable embedded relational database that compiles anywhere go does
- single-user zero-dependency data storage for go apps

## When to choose
- You need an SQL database embedded directly in a Go binary with no CGO or external dependencies
- You want a storage engine written entirely in Go that is easy to cross-compile and distribute
- You are comfortable using the project's own SQL dialect with its custom types, expressions, and pattern matching

## When to avoid
- You need a mainstream, widely supported database such as SQLite, Postgres, or BoltDB with broad tooling and community support
- You require strict standard SQL compatibility or interoperability with existing SQL clients
- You are still importing the old github.com/cznic/ql path, since the repo is archived and the module now lives at modernc.org/ql
- You need multi-user, client-server, or heavy concurrent write workloads

## Facets
- artifact type: library
