## What it is
BRMW is a free, open-source web application for entity-relationship database modeling, letting users create conceptual and logical models and export SQL directly from the browser. It is aimed at making database modeling education simple and accessible, with cloud-stored projects and conversion between conceptual, logical, and physical levels.

## Use cases
- draw entity-relationship diagrams online
- convert conceptual models to logical models
- generate SQL from a database model
- teach database modeling to students
- model relational databases in the browser
- learn database normalization visually

## When to choose
- you need a free, browser-based ER modeling tool for learning or teaching
- you want to convert between conceptual, logical, and physical models and export SQL
- you want to self-host a database modeling application

## When to avoid
- you need production-grade enterprise data modeling with advanced reverse engineering
- you need offline desktop modeling tools
- you need NoSQL modeling support today (still in migration)

## Facets
- artifact type: application
- maturity: active
- function: web-framework, database, gui, editor, data-visualization
- domain: databases, web-development, education, developer-tools
- platform: self-hosted
- tags: entity-relationship-diagram, database-modeling, sql-generation, conceptual-modeling, logical-modeling, nosql-modeling, teaching-tool, web-server, nodejs, docker
