Active Record is the Ruby on Rails ORM that maps database rows to business objects: it manages data persistence and logic without manual SQL.

This framework implements Martin Fowler's Active Record pattern to bridge the gap between Ruby objects and relational databases (PostgreSQL, MySQL, and SQLite). By inheriting from ApplicationRecord, your classes gain built-in methods for CRUD operations and complex associations like has_many or belongs_to. It eliminates the bulk of manual SQL writing: developers use a clean Ruby DSL to query data and manage migrations. Validation logic stays inside the model to ensure data integrity before it hits the disk.

An IDE and OS for agents - lots to cover so will focus on the unifying idea of representing everything an agent needs (variables, schemas, state, UIs) in a single "ORM"
