This Application Design Document (ADD) outlines the proposed architecture, design, and database schema for Berta’s Pizzeria Website (BPW), aiming to facilitate an online ordering system for customers to place pizza orders, register, and manage their orders efficiently. It also describes maintenance functionalities for authorized staff, incorporating agile development principles for iterative enhancements and stakeholder collaboration.

The primary goal of BPW is to enable customers to register, customize, and submit pizza orders through a web interface, while providing Berta’s staff with tools for menu management and reporting. The system aims to improve delivery efficiency and customer experience, thus increasing competitiveness amidst local restaurant rivals.

Introduction

Berta’s Pizzeria has historically operated through traditional means, relying on phone orders and in-store dining, which limits scalability and responsiveness to customer needs. To adapt to contemporary customer expectations and technological shifts, BPW was conceived as a comprehensive online platform, integrating customer engagement, order processing, and staff management within a modern, secure, and scalable web architecture.

Design Overview

The core challenge addressed by BPW is creating an intuitive, reliable, and secure online ordering platform that seamlessly integrates with existing order fulfillment systems while maintaining ease of use for customers and staff alike. The solution encompasses multiple functional areas: customer registration, order customization, payment processing, menu management, and reporting.

System Requirements and Use Cases

Customer registration is the foundation of user engagement, involving input of personal information, email verification, and secure session management. Customers should easily browse the menu, select pizza size and toppings, add sides and beverages, and specify delivery or carryout options. The order review and confirmation process must be user-friendly, allowing modifications before final submission. Payment processing must adhere to security standards, encrypting sensitive data and integrating with third-party payment gateways.

For staff, administrative functionalities include menu management—adding or removing categories and items—and report generation, such as sales summaries and custom data fields tailored to managerial insights. These features are designed to optimize operation efficiency and data-driven decision-making.

Technologies and Architecture

BPW will utilize a LAMP stack (Linux, Apache, MySQL, PHP/Python/Perl) hosted on Host Gator, leveraging cPanel for management. This choice ensures compatibility, security, and scalability. The architecture emphasizes separation of concerns, with distinct layers handling user interface, business logic, and data persistence.

The design applies principles including high cohesion and low coupling, employing patterns such as Model-View-Controller (MVC) to facilitate maintainability. Change management is prioritized through modular design, allowing independent updates to menu data, user management, and reporting modules.

Graphical representations like sequence diagrams, class diagrams, and domain models illustrate interactions and data relationships. These visual tools guide development and ensure clarity across teams.

Class Diagram and Data Implementation

The class diagram details key entities such as Customer, Order, Pizza, Topping, MenuItem, and Staff, with associations representing relationships like customer orders and menu item compositions. Data tables map these classes to concrete database schemas, supporting persistent storage and efficient querying.

For example, the Customer table includes fields for registration information, verification status, and session tokens, supporting secure login processes. The Order table links to Customer and MenuItem entries, capturing order specifics and status updates.

Security and Maintenance

Security protocols involve encrypting payment details, using SSL/TLS for all communications, and implementing role-based access control for staff functionalities. Automated reports facilitate operational oversight, while manual updates to menu items and categories remain accessible to authorized personnel. The design supports incremental updates aligned with Agile principles, accommodating evolving requirements and stakeholder feedback.

Conclusion

BPW exemplifies a disciplined, modular approach to web application design tailored for the hospitality industry. By integrating effective technologies with sound architectural patterns, it aims to deliver a reliable, scalable, and user-friendly platform that enhances Berta’s competitive position and elevates customer satisfaction.
