Mongoid is the official Object-Document Mapper (ODM) framework for MongoDB in Ruby, built on top of the official Ruby MongoDB driver. It provides ActiveRecord-like modeling, querying, and Rails integration for document-based persistence.

Use cases

• map Ruby classes to MongoDB documents
• use MongoDB models in a Rails app like ActiveRecord
• query MongoDB with a Ruby DSL instead of raw driver calls
• define associations and validations for document models
• migrate a Rails app from SQL to MongoDB
• manage nested documents and embedded associations in Ruby

When to choose

• you are building a Ruby or Rails application backed by MongoDB
• you want an ActiveRecord-like API for document data
• you need an officially supported, actively maintained MongoDB ODM

When to avoid

• your project uses a relational database instead of MongoDB
• you prefer lightweight direct driver access without an ORM layer
• you need an ODM for another language or framework
