## What it is
Sequel is a Ruby database toolkit providing a concise DSL for SQL query construction, schema management, and a comprehensive ORM layer for mapping records to Ruby objects. It supports many databases including PostgreSQL, MySQL, SQLite, and Oracle, with advanced features like prepared statements, sharding, and primary/replica configurations.

## Use cases
- query a SQL database from Ruby without raw SQL strings
- map database rows to Ruby objects with an ORM
- run database migrations and schema changes
- set up primary/replica database configurations or sharding
- use prepared statements and bound variables in Ruby
- connect to PostgreSQL, MySQL, or SQLite from a Ruby app

## When to choose
- you want a lightweight, fast Ruby ORM alternative to ActiveRecord
- you need fine-grained SQL query construction with a Ruby DSL
- you need advanced database features like savepoints, two-phase commit, or sharding
- you want a toolkit that works both as a query builder and a full ORM

## When to avoid
- you are not working in Ruby
- you need a NoSQL or document database mapper
- your team already standardizes on ActiveRecord and its ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: orm, database, database-driver
- domain: databases, web-development, backend, developer-tools
- platform: ruby, cross-platform
- tags: sql, query-builder, migrations, connection-pooling, postgresql, mysql, sqlite, activerecord-alternative, migration
