## What it is
DBML (Database Markup Language) is a simple, human-readable DSL for defining and documenting database structures, database-agnostic in design. It ships as a JavaScript core library (@dbml/core) and CLI (@dbml/cli), with companion tools dbdiagram.io for visualization and dbdocs.io for documentation.

## Use cases
- define database schemas in a readable DSL
- document database structures
- convert DBML to SQL DDL for different databases
- visualize database schema as ER diagrams
- generate database documentation from schema files

## When to choose
- you want a database-agnostic, human-readable schema definition language
- you need to document or visualize database structures quickly
- you want to generate SQL for multiple database engines from one schema source

## When to avoid
- you need full DBMS-specific feature coverage like stored procedures or triggers
- you want migrations/versioning tooling rather than schema definition
- your workflow is already covered by ORM schema definitions

## Facets
- artifact type: library
- maturity: active
- function: parser, documentation, developer-tools
- domain: databases, developer-tools, documentation
- platform: cli, cross-platform
- tags: dsl, database-schema, schema-definition, dbdiagram, erd, nodejs
