What problem does it solve?

Defining and maintaining clear relationships between BKnd entities can be complex when dealing with many-to-one, one-to-one, many-to-many, and self-referencing patterns. This Skill provides structured guidance to model relationships, configure fields, and align data navigation for intuitive access.

Core Features & Use Cases

UI & Code Approaches: Learn how to set up relationships via BKnd's Data UI and through code using the em() schema builder.
Relationship Types: Implement many-to-one, one-to-one, many-to-many, and self-referencing relations with proper join/junction logic.
Options & Mappings: Use mappedBy, inversedBy, and connectionTable to customize FK naming and navigation.

Quick Start

Create a schema with entities like users and posts, then define a many-to-one relation from posts to users and a many-to-many relation between posts and tags using em() and relation() calls.
