 # Eighth Assignment: Restaurant 🍕
 
-## Overview 👋
-
-Welcome to your final assignment before the grand project! 🍽️🚀 We’re wrapping things up with a full-stack desktop application that simulates a restaurant ordering system. You’ll build it using **JavaFX** for the UI and **PostgreSQL** for persistent data storage.
-
-You’ll implement essential user flows like **sign-up**, **login**, and **placing orders**, and use **JDBC** for direct interaction with the database. Your journey will bring together everything you've learned in this course — from file-based applications to database-backed systems with a graphical interface.
-  
-## Prerequisites ✅  
-
- Make sure you have installed these programs and services before starting your project:  
-  
-- Git  
-- Java 23  
-- Gradle   
-- PostgreSQL  
-- Scene Builder  
-> 💡 You might need VPN or DNS setting for downloading JavaFX packages using Gradle.  
-> In case of any major problems with gradle, you can create a new project with maven and copy the readme file in the new project.
-  
-## Objectives ✏️
-
-By completing this assignment, you will:
-
-- Build a **full-stack desktop application** that integrates a graphical user interface with a relational database.
-    
-- Understand how to **connect a Java application to a relational database** using JDBC.
-    
-- Gain hands-on experience in **designing and implementing UI using JavaFX**.
-
-## Logic
-
-### Entities
-
-Your project should **at minimum** include the following entities to properly model a simple restaurant ordering system. The following entities are essential for managing users, menu items, and orders:
-
-------
-
-#### 1. **User**
-
-Represents a person using the system (e.g., a customer).
-
-- **Attributes:**
-  - `id`: Unique identifier
-  - `username`
-  - `password`
-  - `email` *(optional)*
-- **Relationships:**
-  - One **User** can place many **Orders**.
-
-------
-
-#### 2. **MenuItem**
-
-Represents a single item on the restaurant's menu.
-
-- **Attributes:**
-  - `id`: Unique identifier
-  - `name`
-  - `description` *(optional)*
-  - `price`
-  - `category` *(optional, useful for the bonus part)*
-- **Relationships:**
-  - A **MenuItem** can appear in many **OrderDetails** (i.e., be ordered in many different orders).
-
-
-> **⚠️ There should be at least 3 items in the menu.**  
-        
-> **💡 You don't have to add a menu item through your app. Inserting items by sql commands in pg admin is enough.**
-
-------
-
-#### 3. **Order**
-
-Represents a single order placed by a user.
-
-- **Attributes:**
-  - `id`: Unique identifier
-  - `userId`: Reference to the `User` who placed the order
-  - `createdAt`: Timestamp of when the order was placed
-  - `totalPrice`: Total cost of the order (can be calculated or stored)
-- **Relationships:**
-  - An **Order** belongs to one **User**.
-  - An **Order** has many **OrderDetails**, each representing a specific item in the order.
-
-------
-
-#### 4. **OrderDetail**
-
-Represents a line item in an order (i.e., a specific menu item and its quantity).
-
-- **Attributes:**
-  - `id`: Unique identifier
-  - `orderId`: Reference to the associated `Order`
-  - `menuItemId`: Reference to the selected `MenuItem`
-  - `quantity`: Number of units of the menu item ordered
-  - `price`: Price per unit at the time of ordering
-- **Relationships:**
-  - An **OrderDetail** belongs to one **Order** and one **MenuItem**.
-  - Multiple **OrderDetails** make up an **Order**.
-
-------
-
-### Entity Relationships Summary
-
-- A **User** ➝ can have many **Orders**.
-
-- An **Order** ➝ belongs to one **User**, and has many **OrderDetails**.
-
-- A **MenuItem** ➝ can appear in many **OrderDetails**.
-
-- An **OrderDetail** ➝ connects one **Order** to one **MenuItem** with quantity and price.
-
-  
-### Scenario
-Your project flow should go through the following steps
-#### Step 1: Login / Sign-Up:
-The customer creates a new account or logs into an existing one to access the restaurant's features.
-* Accounts should contain a **Username** and a **Password**
-  * Having a more detailed account setup is bonus
-* Passwords should be hashed
-
-#### Step 2: Display Menu:
-A menu is displayed to the customer consisting of all the foods available in the restaurant.
-* Menu Items should include " Food Name + Price "
-  * Including the used ingredients is bonus
-
-#### Step 3: Order Food:
-The customer selects desired items and adds them to the cart for checkout.
-* The customer should be able to add or delete selected foods from their order.
-
-#### Step 4: Checkout
-After the order is placed, a detailed receipt is shown with itemized costs and confirmation of the transaction.
-* The receipt has to have the following information:
-  1. Names of the ordered food items
-  2. Quantity of each item
-  3. Price per unit of each item
-  4. Total price for each item (unit price × quantity)
-  5. Total price of the order
-* After the confirmation, the order should be saved to the database
-
-### UI
-The User Interface of your application should include the features listed below (note that this is just a suggested UI implementation and your app can have any design of your choice)
-#### 1. Login / Sign-Up page:
-* A text field and a password field for logging in
-* A text field and two password fields for signing up (two pass fields for verifying the password)
-* Note that errors for common problems such as the ones listed below should be displayed to the user:
-  * "Username unavailable" in login
-  * "Incorrect Password" in login
-  * "Username is already taken" in sign up
-  * etc.
-#### 2. Ordering page:
-* On the left side of the screen a list of the customer's currently selected food
-  * The customer must have the ability to increase or decrease the number of selected items
-  * Also include a "Checkout" button under the order so the customer can end their selection
-* On the right side, the menu of the restaurant
-  * The menu items should be buttons so the customer can select them
-  * It can be implemented as a simple table showing the food and its price or by using small components like bubbles that get added to the page
-* Implementing a "Back" button is bonus so that the user can return to the login page
-#### 3. Checkout page:
-* As explained in the last section, display each of the necessary information either in a table or any other way you see fit
-* Implement a "Set Order" button to finalize the order and add it to the database
-* Display something like "Thanks for your purchase :)" message to the customer
-* Give the options to order again or leave to the login/sign-up pages and implement the functionality for each button correspondingly
-## Bonus
-
-* Smooth and consistent navigation, allowing users to move forward and backward between pages without breaking the app’s functionality.
-* Include food categories (e.g., Fast Food, Traditional, Italian, etc.) to organize the menu and help users find items more easily.
-* The ability to view the order history of a customer.
-* Using images for displaying menu items.
-* Being able to add more menu items as a restaurant admin.
-
-## Evaluation 📃
-
-Your submission will be evaluated based on the following criteria:
-
-- **Database Design and Integration (PostgreSQL)**
-   You must design your database schema properly with clear relationships between entities (as explained in the Logic section). The application should interact with the PostgreSQL database to:
-  - Store and retrieve user data
-  - Save and update orders and their details
-  - Load menu items dynamically
-  - Include your initial sql codes as a separate file in the project
-- **User Interface (JavaFX)**
-   The UI should be clean, user-friendly, and visually organized. Use JavaFX effectively to implement different screens (e.g., login/signup, ordering, order summary).
-- **Code Quality and Structure**
-   Your code should be clean, modular, and follow object-oriented principles. Use appropriate naming, structure your classes and packages well, and avoid redundant or duplicate code.

+## 👋 Overview
+
+Welcome to the Restaurant Ordering System\! This project is a full-stack desktop application developed as the final assignment for the course. It simulates a restaurant's ordering process, allowing users to sign up, log in, browse a menu, place orders, and view their order history. Administrators have the ability to manage menu items.
+
+The application features a Graphical User Interface (GUI) built with **JavaFX** and utilizes a **PostgreSQL** database for persistent data storage. Direct database interaction is handled via **JDBC**. This project brings together concepts from file-based applications to database-backed systems with a graphical interface.
+
+-----
+
+## 💻 Technologies Used
+
+* **Programming Language:** Java (Targeting JDK 24, compatible with recent versions like 17/21+)
+* **User Interface (UI):** JavaFX
+* **Database:** PostgreSQL
+* **Database Connectivity:** JDBC (Java Database Connectivity)
+* **Build Tool:** Gradle
+* **UI Design Tool (Recommended):** Scene Builder
+
+-----
+
+## ✅ Prerequisites
+
+Before running or developing this project, ensure you have the following installed:
+
+* **Git:** For version control (cloning the project).
+* **Java JDK:** Version 24 (as specified in project description) or a compatible version (e.g., JDK 17, 21).
+* **Gradle:** For building the project and managing dependencies. The project includes a Gradle Wrapper (`gradlew`) for consistent builds.
+* **PostgreSQL:** The relational database server.
+* **pgAdmin (or similar SQL client):** For managing the PostgreSQL database and running the initial schema script.
+* **Scene Builder (Optional but Recommended):** For visually designing or inspecting the JavaFX FXML files.
+
+-----
+
+## ✏️ Objectives
+
+This project aims to:
+
+* Build a **full-stack desktop application** integrating a GUI with a relational database.
+* Demonstrate understanding of connecting a Java application to a relational database using **JDBC**.
+* Provide hands-on experience in designing and implementing a UI using **JavaFX**.
+* Implement core application logic for user management, menu display, order processing, and data persistence.
+
+-----
+
+## 🚀 Project Setup & Running Instructions
+
+### 1\. Database Setup
+
+* **Ensure PostgreSQL Server is Running:** Start your PostgreSQL server instance.
+* **Create a Database:**
+  * Using pgAdmin or another SQL client, connect to your PostgreSQL server.
+  * Create a new database (e.g., name it `restaurant_db`).
+* **Run the Schema Script:**
+  * Locate the `schema.sql` file in the `sql/` directory of this project.
+  * Open the Query Tool for your newly created `restaurant_db`.
+  * Copy the entire content of `schema.sql` and execute it. This will create all necessary tables (`User`, `MenuItem`, `Order`, `OrderDetail`) and insert sample menu items.
+* **Configure Database Connection in Java:**
+  * Open the file: `src/main/java/ap/restaurant/restaurant/util/DatabaseUtil.java`.
+  * Update the following constants with your actual PostgreSQL connection details:
+    ```java
+    private static final String DB_URL = "jdbc:postgresql://localhost:5432/your_database_name"; // Replace your_database_name
+    private static final String DB_USER = "your_db_user"; // Replace your_db_user
+    private static final String DB_PASSWORD = "your_db_password"; // Replace your_db_password
+    ```
+
+### 2\. Building & Running the Application
+
+* **Clone the Project (if applicable):**
+  ```bash
+  git clone <repository-url>
+  cd Eighth-Assignment-Restaurant
+  ```
+* **Using Gradle (Recommended):**
+  * Open a terminal or command prompt in the root directory of the project.
+  * Make the Gradle wrapper executable (on Linux/macOS, one-time setup):
+    ```bash
+    chmod +x ./gradlew
+    ```
+  * Run the application:
+    ```bash
+    ./gradlew run  # On Linux/macOS
+    gradlew run   # On Windows
+    ```
+  * The first run might take longer as Gradle downloads dependencies.
+* **Running from IntelliJ IDEA (or similar IDE):**
+  1.  Open the project in IntelliJ (File -\> Open -\> navigate to the project's root folder).
+  2.  Trust the project and allow IntelliJ to import/sync with Gradle. This will download dependencies.
+  3.  Ensure the Project SDK is correctly set (e.g., JDK 24).
+  4.  Ensure IntelliJ is configured to use Gradle from the `'gradle-wrapper.properties' file` (Settings -\> Build, Execution, Deployment -\> Build Tools -\> Gradle).
+  5.  Locate the main class `ap.restaurant.restaurant.HelloApplication`.
+  6.  You can either run the `main` method directly from IntelliJ or use the run configuration automatically created by the Gradle `application` plugin (usually found in the run configurations dropdown).
+
+-----
+
+## 🏛️ System Architecture & Design Choices
+
+This project follows a layered architecture, loosely based on the Model-View-Controller (MVC) pattern, to organize its components and responsibilities.
+
+* **Model:**
+  * Represented by the Java classes in the `ap.restaurant.restaurant.model` package (`User.java`, `MenuItem.java`, `Order.java`, `OrderDetail.java`).
+  * These are Plain Old Java Objects (POJOs) that encapsulate the application's data structure, mirroring the database entities.
+* **View:**
+  * Implemented using **JavaFX FXML**. Files are located in `src/main/resources/ap/restaurant/restaurant/`.
+  * FXML provides a declarative way to define the user interface structure, separating it from the application logic. Scene Builder can be used to design these views.
+* **Controller (JavaFX Controllers):**
+  * Located in the `ap.restaurant.restaurant.controller` package (e.g., `LoginSignUpController.java`, `OrderingController.java`).
+  * These classes act as the bridge between the View (FXML) and the Model/Business Logic. They handle user interactions from the FXML views, process input, and update the views accordingly.
+* **Data Access Objects (DAO):**
+  * Found in the `ap.restaurant.restaurant.dao` package (e.g., `UserDAO.java`, `MenuItemDAO.java`, `OrderDAO.java`).
+  * These classes encapsulate all database interaction logic using **JDBC**. They provide CRUD (Create, Read, Update, Delete) operations for the model entities, abstracting the database specifics from the controllers.
+* **Utility Classes:**
+  * The `ap.restaurant.restaurant.util` package contains helper classes:
+    * `DatabaseUtil.java`: Manages JDBC connections to the PostgreSQL database.
+    * `PasswordUtil.java`: Handles password hashing (using SHA-256 for this project) and verification. For a production environment, stronger algorithms like BCrypt or SCrypt with unique salts per user would be recommended.
+* **Main Application Class:**
+  * `HelloApplication.java` is the entry point for the JavaFX application. It manages scene switching and initializes the primary stage.
+
+### Database Design Rationale:
+
+* **Normalization:** The database schema is designed with normalization principles in mind to reduce data redundancy and improve data integrity.
+  * `User`, `MenuItem`, and `Order` are distinct entities.
+  * The `OrderDetail` table serves as a join table to model the many-to-many relationship between `Order` and `MenuItem`, also capturing the quantity and price per unit at the time of the order (crucial for historical accuracy if menu prices change).
+* **Primary and Foreign Keys:** Enforce relationships and ensure referential integrity.
+* **Data Types:** Chosen to appropriately represent the data (e.g., `DECIMAL` for prices, `TIMESTAMP WITH TIME ZONE` for order creation).
+* **Indexes:** Added on foreign key columns to improve query performance for fetching orders and order details.
+* **Cascade Rules:** `ON DELETE CASCADE` is used judiciously (e.g., deleting a user also deletes their orders) while `ON DELETE RESTRICT` protects `MenuItem`s from being deleted if they are part of historical orders.
+
+-----
+
+## ✨ Core Features Implemented
+
+* **User Authentication:**
+  * **Sign-Up:** New users can create an account with a username and password. Passwords are **hashed** before being stored in the database. Email is optional.
+  * **Login:** Existing users can log in with their credentials. The system differentiates between regular users and administrators.
+* **Menu Display:**
+  * A dynamic menu is displayed to the customer, loading items from the `MenuItem` table in the database.
+  * Menu items show at least "Food Name + Price".
+* **Food Ordering & Cart Management:**
+  * Customers can select desired menu items and add them to their virtual cart.
+  * Quantities of items in the cart can be increased or decreased.
+  * Items can be removed from the cart.
+  * The total price of the cart is updated dynamically.
+* **Checkout Process:**
+  * After finalizing their selections, customers proceed to checkout.
+  * A detailed receipt/order summary is shown, including:
+    * Names of ordered food items.
+    * Quantity of each item.
+    * Price per unit of each item.
+    * Total price for each item (unit price × quantity).
+    * Total price of the entire order.
+  * Upon confirmation, the order (including `Order` and `OrderDetail` records) is saved to the PostgreSQL database.
+* **Error Handling:**
+  * User-facing error messages are provided for common issues like incorrect login credentials, username already taken, empty fields, etc.
+
+-----
+
+## ⭐ Bonus Features Implemented
+
+1.  **Smooth and Consistent Navigation:**
+
+  * The application allows users to move between different pages (Login/Sign-Up, Ordering, Checkout, Order History, Admin) through dedicated buttons and logical flows managed by `HelloApplication.java`.
+
+2.  **Food Categories:**
+
+  * Menu items can be assigned categories (e.g., "Pizza", "Burgers", "Drinks").
+  * The ordering page includes a `ComboBox` allowing customers to filter the displayed menu items by category, enhancing usability.
+
+3.  **View Order History:**
+
+  * Logged-in customers can access a dedicated page to view their past orders.
+  * Each order in the history displays its ID, creation date, total price, and a detailed breakdown of the items included (name, quantity, price per unit, item total). Orders are displayed in an `Accordion` for a clean presentation.
+
+4.  **Using Images for Displaying Menu Items:**
+
+  * The `MenuItem` entity includes an `image_url` field.
+  * The ordering page attempts to load and display an image for each menu item.
+  * A placeholder image (`src/main/resources/images/placeholder.png`) is used if an item's specific image is not found or the URL is invalid.
+  * **To fully utilize this:** Actual image files need to be placed in the `src/main/resources/images/` directory, and the `image_url` in the database for `MenuItem` records must correctly point to these files (e.g., `images/margherita.png`).
+
+5.  **Admin: Add/Manage Menu Items:**
+
+  * Users can be designated as administrators (via the `is_admin` flag in the `User` table, settable during sign-up).
+  * Admin users are directed to a "Menu Management" page after login.
+  * This page allows admins to:
+    * View all current menu items in a table.
+    * Add new menu items by providing name, price, category, description, and image URL.
+    * Select an existing item from the table to populate an edit form.
+    * Update the details of selected menu items.
+    * Delete menu items (with a confirmation dialog).
+  * The form includes a `ComboBox` for categories that is populated with existing categories and also allows typing in new ones.
+
+-----
+
+## 📁 Code Structure
+
+The project follows a standard Maven/Gradle directory structure:
+
+* **`src/main/java/ap/restaurant/restaurant/`**: Contains all Java source code.
+  * **`controller/`**: JavaFX controller classes that manage UI logic.
+  * **`dao/`**: Data Access Object classes for database interactions.
+  * **`model/`**: Entity classes representing the data model.
+  * **`util/`**: Utility classes (e.g., `DatabaseUtil`, `PasswordUtil`).
+  * **`HelloApplication.java`**: The main entry point for the JavaFX application.
+  * **`module-info.java`**: Java Platform Module System module descriptor.
+* **`src/main/resources/ap/restaurant/restaurant/`**: Contains FXML files for UI layout and other resources.
+  * **`images/`**: (To be created by the user) For storing menu item images.
+* **`sql/`**: Contains the database schema setup script (`schema.sql`).
+* **`build.gradle`**: Gradle build script for managing dependencies and build tasks.
+
+-----
+
+## 💡 Potential Future Enhancements
+
+* **Stronger Password Hashing:** Implement BCrypt or SCrypt with unique salts per user for production-level security.
+* **Enhanced Input Validation:** More comprehensive client-side and server-side validation.
+* **Detailed Order Status:** (e.g., "Preparing", "Out for Delivery", "Delivered") - would require schema changes.
+* **User Profile Management:** Allow users to update their email or password.
+* **More Sophisticated UI/UX:** Animations, custom styling beyond default JavaFX.
+* **Reporting/Analytics:** For admin users (e.g., popular items, sales reports).
+* **Unit and Integration Testing:** Implement JUnit tests for DAOs, services, and controllers.
+
+-----
+
+## 📃 Notes on Evaluation Criteria (Self-Assessment)
+
+* **Database Design and Integration (PostgreSQL):**
+  * The database schema is designed with clear relationships as per the project logic section.
+  * The application interacts with PostgreSQL via JDBC to store/retrieve user data, save/update orders and details, and load menu items dynamically.
