Backbone.Relational

Enables defining one-to-one, one-to-many, and many-to-one relationships, extending Backbone's basic models to handle interconnected data structures as highlighted in the key features.

Handles setting and getting of related models automatically, maintaining data consistency across the graph and reducing boilerplate code, per the documentation.

Integrates directly with Backbone.js by extending the core Model class, allowing easy adoption in existing Backbone applications without major rewrites.

Follows Backbone's lightweight approach, adding essential relational features without becoming a heavy ORM, as stated in the philosophy section.
