## What it is
Ecto is a toolkit for data mapping and language-integrated queries in Elixir, providing schemas, changesets, and a composable query DSL. It is commonly paired with ecto_sql to work with databases like PostgreSQL and MySQL.

## Use cases
- map database rows to elixir structs
- write type-safe database queries in elixir
- validate and cast form data with changesets
- build a phoenix web app with database persistence
- query postgresql from elixir
- define database schemas in elixir

## When to choose
- you are building an Elixir application that needs database access or data validation
- you want a composable, functional query DSL instead of raw SQL strings
- you need to map external data sources into validated Elixir structs

## When to avoid
- your project is not written in Elixir or on the Erlang VM
- you need an ORM with active-record-style associations and migrations out of the box without the ecto_sql companion package
- you prefer raw SQL or a lightweight query builder for simple scripts

## Facets
- artifact type: library
- maturity: stable
- function: orm, database, database-driver, serialization, type-system
- domain: databases, backend, web-development, developer-tools
- platform: elixir, jvm, cross-platform
- tags: data-mapping, query-dsl, elixir, changesets, sql-adapters, schema-validation
