What problem does it solve?

Explicitly define entity ownership and relationship cardinality to prevent data anomalies and hard-to-trace bugs across domains and APIs.

Core Features & Use Cases

• Explicitly model one-to-one, one-to-many, many-to-one, and many-to-many relationships with clearly defined ownership and foreign key behavior.
• Define join tables or link entities where needed and specify cascade rules to avoid unintended deletions.
• Design read and serialization strategies that prevent recursive payloads and keep API surfaces stable.

Quick Start

Model the relationship between two entities by selecting cardinality, designating the owner side and foreign key behavior, and plan DTO boundaries to avoid recursive payloads.
