    Email VARCHAR(100),
    UserType ENUM('Admin', 'Manager', 'Staf') NOT NULL
);
CREATE TABLE Room (
    RoomId INT PRIMARY KEY AUTO_INCREMENT,
    RoomNumber VARCHAR(20) NOT NULL,
    RoomType VARCHAR(50) NOT NULL,
    Price DECIMAL(10, 2) NOT NULL,
    Status ENUM('Available', 'Occupied', 'Resrved') NOT NULL
);
CREATE TABLE Order (
    OrderId INT PRIMARY KE AUTO_INCREMENT,
    UserId INT,
    RoomId INT,
    CheckInDate DATE NOT NULL,
    CheckOutDate DATE NOT NULL,
    TotalAmount DECIMAL(10, 2) NOT NULL,
    Status ENUM('Reserved', 'CheckedIn', 'CheckedOut', 'Cancelled') NOT NULL,
    FOREIGN KEY (UserId) REFERENCES User(UseId),
    FOREIGN KEY (RoomId) REFERENCES Room(RoomId)
);
CREATE TABLE Customer (
    CustomerId INT PRIARY KEY AUTO_INCREMENT,
    OrderId INT,
    FirstName VARCHAR(50) NOT NULL,
    LastName VARCHAR(50) NOT NULL
    Email VARCHAR(100),
    Phone VARCHAR(20),
    FOREIGN KEY (OrderId) REFERENCES Order(OrderId)
);

Configure development environment
Integrated development tool selection

Chapter 5: System Implementation

5.1 Implementation of database table structure

Database creation and initialization

5.2 Back-end business logic implementation

Implementation of Spring MVC controller
Implementation of MyBatis persistence layer

Part of the code for the backend implementation module:

Entity class:

// User.java
public class User {
    private int userId;
    private String userName;
    private String password;
    private String email;
    private UserType userType; // Enum: Admin, Manager, Staff
    // Getters and setters
}

// Room.java
public class Room {
    private int roomId;
    private String roomNumber;
    private String roomType;
    private BigDecimal price;
    private RoomStatus status; // Enum: Available, Occupied, Reserved
    // Getters and setters
}

// Order.java
public class Order {
    private int orderId;
    private User user;
    private Room room;
    private Date checkInDate;
    private Date checkOutDate;
    private BigDecimal totalAmount;
    private OrderStatus status; // Enum: Reserved, CheckedIn, CheckedOut, Cancelled
    private List<Customer> customers;
    private List<Service> services;
    // Getters and setters
}

// Customer.java
public class Customer {
    private int customerId;
    private Order order;
    private String firstName;
    private String lastName;
    private String email;
    private String phone;
    // Getters and setters
}

// Service.java
public class Service {
    private int serviceId;
    private Order order;
    private String description;
    private BigDecimal amount;
    // Getters and setters
}

Service layer:

// UserService.java
public interface UserService {
    User getUserByI(int userId);
    User getUserByUsername(String username);
    void addUser(User user);
    void updateUser(User user);
    void deleteUser(int userId);
    // Other methods as needed
}

// RoomService.java
public interface RoomService {
    Room getRoomById(int roomId);
    List<Room> getAllRooms();
    void addRoom(Room room);
    void updateRoom(Room room);
    void deleteRoom(int romId);
    // Other methods as needed
}

// OrderService.java
public interface OrderService {
    Order getOrderById(int orderId);
    List<Order> getOrdersByUserId(int userId);
    void addOrder(Order order);
    void updateOrder(Order order);
    void deleteOrder(int orderId);
    // Other methods as needed
}

// CustomerService.java
public interface CustomerService {
    Customer getCustomerById(int customerId);
    List<Customer> getCustomersByOrderId(in orderId);
    void addCustomer(Customer customer);
    void updateCustomer(Customer customer);
    void deletCustomer(int customerId);
    // Other methods as needed
}

// ServiceService.java
public interface ServiceService {
    Service getServiceById(it serviceId);
    List<Service> getServicesByOrderId(int orderId);
    void addService(Service service)
    void updateService(Service service);
    void deleteService(int serviceId);
    // Other methods as needed
}

5.3 Front-end interface implementation

Design and implementation of mobile interface

Front-end code:

<template>
  <div>
    <router-view></router-view>
  </div>
</template>

<script>
export default {
  name: 'Main',
}
</script>

<style>
/* Add your styles here */
</style>
<template>
  <div>
    <h2>User Management</h2>
    <!-- Add user management components and features here -->
  </div>
</template>

<script>
export default {
  name: 'UserManagement',
}
</script>

<style>
/* Add your styles here */
</style>
<template>
  <div>
    <h2>Room Management</h2>
    <!-- Add room management components and features here -->
  </div>
</template>

<script>
export default {
  name: 'RoomManagement',
}
</script>

<style>
/* Add your styles here */
</style>
