Architectural Design

This directory contains the architectural design of the system.

Components

The components of the system are as follows:

  1. Schedulers: The schedulers are responsible for scheduling the orders and the cpee callback urls.

  2. Order Management System: The OMS acts as a interface between the QR codes and the order_scheduler.

  3. QR Code Web Application: The qr_website and qr_weblogic are responsible for generating the QR codes, displaying the QR codes and the web logic for displaying the order status.

  4. Recipe Service: The recipe server is responsible for the recipe management.

  5. Simulator: The simulator is responsible for simulating the consume of liquer and the mixing of the liquer.

  6. Order Store: The order store is responsible for storing the orders and the order status.
