SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides the AI in designing and implementing backend data models that are consistent, well-structured, and adhere to best practices for database interaction and object-relational mapping (ORM).

Core Features & Use Cases

  • Standardized Model Structure: Ensures models follow consistent naming, relationships, and attribute definitions.
  • Data Integrity: Guides the AI to define appropriate data types, constraints, and validations within models.
  • Use Case: When adding a new entity to the application (e.g., a 'Project' entity), this Skill ensures the AI defines the corresponding backend model with correct attributes, relationships to other models (like 'User' or 'Task'), and appropriate validation rules.

Quick Start

Use the 'Backend Models' skill to define the new 'Product' data model, including its attributes and relationships.

FAQPage Schema
How do I design backend data models that enforce consistency across my application?

Backend models enforce consistency through standardized naming conventions, type annotations, validation schemas, and interface contracts. Define models with consistent attribute structures, relationships between entities, and serialization patterns aligned with your repository standards to ensure data integrity across development and code review.

What's the best way to structure database models with proper relationships and constraints?

Structure models by defining appropriate data types, validation rules, and relationships to other entities. Apply naming conventions, add documentation, and use ORM patterns that specify constraints and attribute definitions, ensuring models interact correctly with your database and maintain referential integrity.

How do I ensure my backend models follow ORM best practices?

Apply standardized ORM patterns including proper type annotations, serialization and deserialization logic, validation schemas, and naming conventions. Document relationships between models and align implementation with repository standards to support consistent database interaction across your application.

Can I use backend models to prevent data integrity issues?

Yes. Define appropriate data types, constraints, and validation rules within models to enforce data integrity. Consistent model structure with relationship definitions and validation schemas prevents invalid states and ensures reliable database operations across development and refactoring scenarios.

What should I do when adding a new entity to my application?

Define the entity's backend model with consistent attributes, relationships to existing models, appropriate validation rules, type annotations, and documentation. Align naming and structure with repository standards and ORM patterns to integrate the new entity reliably into your application.

Why do backend models need serialization and deserialization patterns?

Serialization and deserialization patterns ensure models convert consistently between in-memory objects and external formats like JSON or database storage. Standardized patterns prevent data loss, maintain type safety, and enable reliable model interaction across APIs, persistence layers, and code review.
