Flagship Project Architecture

Name: BiteTrack Backend v2

A production-grade reboot of the BiteTrack system focusing on inventory, order management, and core transactional processes using FastAPI.

Core Architectural Layout

The system follows a layered architecture to decouple routing, validation, business rules, and database access.

    Services -->|Query / Mutate| DB[SQLAlchemy Models]
    DB -->|Read/Write| Postgres[(PostgreSQL Database)]

Layers:

  1. Routers (routers/): Handles HTTP routing, status codes, and security dependency injections.
  2. Schemas (schemas/): JSON serialization, deserialization, and strict input/output verification.
  3. Services (services/): Orchestrates business actions, processes transactions, and wraps DB actions.
  4. Models (models/): Represents relational tables mapped to PostgreSQL.
