Hotel Alura - Java Application with Hibernate ORM

Hotel Alura is a simple Java application designed for managing hotel-related information using Hibernate as an Object-Relational Mapping (ORM) tool. This application allows you to perform CRUD (Create, Read, Update, Delete) operations on hotel entities, utilizing the power of Hibernate to interact with the underlying relational database. It has a basic login with the corresponding procedure to save information about reserves and huespeds. This project follow the DAO pattern and MVC pattern.

The package Entities contains the classes that represent the tables in the database. The package DAO contains the classes that make the connection with the database and the methods to save, update, delete and read the information. The package Controller contains the classes that make the connection between the view and the model. The package View contains the classes that show the information to the user and receive the information from the user.

Features

User Authentication System

Only hotel members should have access to the system.

Reservation Management for Clients:

Create, edit, and delete reservations for clients.

Comprehensive Database Search:

Retrieve all information from both clients and reservations stored in the database.

Guest Data Management:

Reservation Cost Calculation:

Automatically calculate the reservation cost based on the number of days and a daily rate that can be set by you. For example, if a reservation is for 3 days and the daily rate is $20, the system should calculate and display the total cost (3 days * $20 = $60) before saving the reservation.
