Summary: Designing a Restaurant Management System
Explore the design of a restaurant management system by understanding its requirements, key classes, and interactions. Learn how to apply object-oriented design principles like SOLID and patterns including Strategy, Template Method, and Composite to model reservations, orders, payments, and notifications effectively.
Now that you’ve completed the restaurant management system case study, let’s take a moment to reflect on and consolidate what we’ve learned. We’ll revisit the key system requirements, identify the core classes along with their responsibilities and relationships, and highlight the major design principles applied. We’ll also examine how objects interact within the system and walk through the overall workflow to understand how the components come together to achieve the desired functionality.
Key requirements
Below are the core functional and non-functional requirements for the restaurant management system:
The restaurant can have multiple branches, each with unique menus and table configurations.
Waiters can create and update orders for tables, adding multiple items per person.
Customers and receptionists can search for tables and make, modify, or cancel reservations.
The system can provide real-time information on available tables for walk-in customers.
The system notifies customers as their reservation time approaches.
Customers can pay bills using credit cards or cash; servers process payments.
Managers can update branch menus and table layouts.
The system automatically updates table statuses after reservations and payments. ...
