SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

GigLedger's database design requires a consistent DTO-to-domain mapping, caching strategy, and security rules to scale; this skill provides a structured approach to design, document, and validate data models.

Core Features & Use Cases

  • Define collection schemas and corresponding DTOs that mirror database structures
  • Transform DTOs to domain models for business logic and UI consumption
  • Plan caching strategies, invalidation rules, and secure access patterns
  • Use Case: design schema for a new feature module (e.g., invoices) with cost-aware queries

Quick Start

Draft a DTO and domain model aligned with docs/05_data_model_and_schema.md for a new collection

FAQPage Schema
How do I design a scalable database schema for a new feature module?

Design scalable database schemas by drafting DTOs that mirror collection structures, then transforming them into domain models for business logic. This approach ensures consistent data access patterns, performance, and cost control for new feature modules like invoices.

What's the best way to map DTOs to domain models for business logic?

Map DTOs to domain models by applying repository patterns and standardized data transformations. This separates database structures from business logic and UI consumption, ensuring consistent data access patterns across services.

Does this schema design approach work for modeling users and transactions across services?

This schema design approach works for modeling users, transactions, and related data flows across services. It standardizes DTOs, domain models, and caching rules to ensure consistent data access patterns and performance.

How do I enforce security constraints and cost control in database schema design?

Enforce security constraints and cost control by aligning schema designs with standardized data model documentation. This structured approach validates data models, enforces repository patterns, and optimizes cost-aware queries.
