Restaurant Booking System

A modern, efficient online reservation system designed for restaurant chains, featuring real-time availability, payment integration, and comprehensive customer management.

Project Overview

This booking management system was developed for a growing restaurant chain that needed to streamline their reservation process across multiple locations. The system provides customers with a seamless booking experience while giving restaurant staff powerful tools to manage reservations, table assignments, and customer data.

The Challenge

The restaurant chain was facing several operational challenges with their existing reservation process:

Operational Issues

• Manual Phone Bookings: 80% of reservations came via phone, tying up staff time
• Overbooking Problems: Frequent double-bookings led to customer dissatisfaction
• No Centralized System: Each location used different methods to track reservations
• Limited Visibility: Management couldn't see real-time booking trends
• No-Show Tracking: Unable to effectively manage no-shows

Technical Requirements

• Real-time Availability: System must show accurate table availability
• Concurrent Bookings: Handle multiple users booking simultaneously
• Multi-location Support: Manage multiple restaurant locations
• Payment Integration: Require deposits for large parties
• Customer Database: Track customer preferences and history

The Solution

We developed a comprehensive booking system with focus on reliability, user experience, and operational efficiency:

Technical Architecture

Frontend

Built with Next.js and modern React patterns:

// Real-time availability check
const checkAvailability = async (
  restaurantId: string,
  date: Date,
  partySize: number,
  timeSlot: string
) => {
  const response = await fetch('/api/availability', {
    method: 'POST',
    body: JSON.stringify({
      restaurantId,
      date,
      partySize,
      timeSlot,
    }),
  });
  
  return response.json();
};

Backend

Database Design

• Prisma ORM for type-safe database operations
• PostgreSQL for reliable data storage
• Database-level locking to prevent double bookings
• Transaction management for data consistency

Key Technical Implementations

1. Concurrent Booking Prevention

// Prevent double bookings with database transactions
await prisma.$transaction(async (tx) => {
  const availability = await tx.table.findFirst({
    where: {
      id: tableId,
      reservations: {
        none: {
          date: requestedDate,
          timeSlot: requestedTime,
          status: 'confirmed',
        },
      },
    },
  });
  
  if (!availability) {
    throw new Error('Table not available');
  }
  
  const reservation = await tx.reservation.create({
    data: { tableId, date, timeSlot, customerId },
  });
  
  return reservation;
});

2. Real-time Availability Calculation

• Considers table capacity and party size
• Accounts for buffer time between reservations
• Handles special events and closures
• Dynamic pricing for peak hours

3. Automated Notifications
