ROAR Backend Architecture: Repository Pattern and Multi-Database Strategy

Overview

This documentation covers the ROAR backend architecture, which implements a repository pattern to provide a flexible, maintainable, and database-agnostic approach to data access.

Key Components

• Repository Pattern: Three-tier approach with base interfaces, specialized interfaces, and concrete implementations
• Service Layer: Business logic orchestration with dependency injection
• Multi-Database Strategy: Architecture designed to support multiple database implementations
• Type Safety: Comprehensive TypeScript interfaces and generics
• Error Handling: Specialized error hierarchy for precise error handling

Current Implementation

The current implementation is built around Firebase/Firestore, but the architecture is designed to support additional database implementations in the future.
