## What it is
ActiveGraph (formerly Neo4j.rb) is an Active Model-compliant object-graph mapper (OGM) for the Neo4j graph database in Ruby. It provides ActiveRecord-style conventions including properties, validations, callbacks, associations, and a chainable query builder for graph queries.

## Use cases
- use neo4j graph database from ruby with activerecord-like models
- build cypher queries with a chainable query builder
- define node and relationship models with validations and callbacks
- integrate neo4j into a rails application
- model graph relationships as first-class entities in ruby
- run migrations and manage constraints for a neo4j database

## When to choose
- you are a ruby or rails developer working with neo4j
- you want an ActiveRecord-familiar API over a graph database
- you need graph traversals expressed as chainable, composable queries
- you want models for both nodes and relationships

## When to avoid
- you use a relational or document database instead of neo4j
- you need a low-level driver only (use neo4j-ruby-driver directly)
- your project is not on the ruby/jvm ecosystem
- you need an ORM for SQL databases
