A Ruby gem providing an ActiveRecord-like base class backed by in-memory hashes, YAML files, or custom file data sources instead of a database. It supports ActiveRecord-style associations like has_many and belongs_to, letting static data models drop into Rails apps seamlessly.

Use cases

• use static lookup data like countries in Rails forms without a database
• replace ActiveRecord models with hash-backed models for seed or reference data
• test gems or plugins that rely on ActiveRecord behavior without a database
• load model data from YAML files instead of a database table
• seamlessly upgrade hash-backed models to full ActiveRecord models later

When to choose

• you have small, static, readonly datasets in a Rails app
• you want ActiveRecord-like APIs for data that lives in hashes or YAML files
• you need database-free models for fast test suites

When to avoid

• you need writable, persistent data with queries across large datasets
• your data changes at runtime and must be stored in a real database
• you are not working in Ruby or a Rails-compatible environment
