SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Poorly defined database models lead to data inconsistencies, difficult relationships, and validation challenges, complicating backend development. This Skill ensures robust data modeling with ORM best practices, simplifying database interactions and maintaining data integrity.

Core Features & Use Cases

  • Data Types & Constraints: Defines appropriate data types and enforces database-level constraints.
  • Relationships Management: Establishes clear relationships (one-to-many, many-to-many) between models.
  • Model Validation: Implements validation rules at the model level for data consistency.
  • Use Case: When defining a new Product model, use this Skill to ensure it has appropriate data types for price and quantity, establishes a foreign key relationship to a Category model, and includes created_at/updated_at timestamps.

Quick Start

Define a new Order backend model with appropriate data types for order items and total amount, establishing a one-to-many relationship with the User model.
