🕵️ Plagiarism Detection System (Spring Boot)

This project is a Plagiarism Detection System developed using Java Spring Boot. It helps in detecting textual similarities between documents, code files, or custom inputs.

✅ Features

• Upload two documents (TXT, PDF, or DOCX).
• Select comparison algorithm (TF-IDF or Cosine Similarity).
• Show similarity percentage.
• Highlight matching sections.
• Display detailed similarity report on the UI.

🛠️ Technologies Used

• Java 17+
• Spring Boot
• Thymeleaf (UI templating)
• Bootstrap (styling)
• SQL Server (database)
• Apache POI / PDFBox (document parsing)
• Cosine Similarity / TF-IDF (algorithm)
• Hibernate (JPA)

▶️ How to Run

1. Clone the repository:

   git clone https://github.com/your-repo/Spring_Boot_UI_Based_Projects.git

2. Open in your IDE (e.g., IntelliJ, Eclipse).

3. Make sure SQL Server is running and update application.properties:

   spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=PlagiarismDB
   spring.datasource.username=your_username
   spring.datasource.password=your_password

4. Run the project using:

   mvn spring-boot:run

5. Access the app at: http://localhost:8080

📌 Notes

• Ensure dependencies like Apache POI or PDFBox are included in pom.xml.
• This system can be extended to check for code plagiarism using token or AST-based methods.
• Frontend allows drag-drop or browse-upload methods.

🛒 Ecommerce Management System (Spring Boot)

This is a Java Spring Boot based simulation of an Ecommerce Management System. It includes a frontend using HTML (Thymeleaf), backend RESTful services, and implementation of various Data Structures like Linked List, Queue, Graph, Array, and Binary Search Tree to manage internal operations.

---

✅ Features

👥 Customer Panel

• Register as a new customer
• View available products
• Place orders for selected products

🛠️ Admin Panel

• Add new products to inventory
• Maintain product catalog
• View placed orders (simulation logic)

🧠 Core Concepts

This project demonstrates the use of fundamental Data Structures & Algorithms:

• LinkedList: To store product inventory
• Array: For managing user data
• Queue: For order processing
• Binary Search Tree (BST): For organizing product catalog
• Graph: To simulate order relations or dependencies

---

🚀 Getting Started

📋 Prerequisites

• Java 17+
• Maven
• Spring Boot
• Any IDE (IntelliJ / Eclipse)

▶️ Run the App

1. Clone the repo:

   git clone https://github.com/your-user/Ecommerce-Simulation.git
   cd Ecommerce-Simulation

2. Start SQL Server (if needed) and configure application.properties accordingly.

3. Build and run:

   mvn spring-boot:run

4. Open in browser: http://localhost:8080

🧪 Example Use Cases

• A user opens the site, registers, and browses products.
• The admin adds new items to the system.
• The user selects a product and places an order.
• Data Structures process and simulate these actions behind the scenes.

---

🌐 UI Technology

• Thymeleaf (HTML templating engine)
• Bootstrap (optional: styling for UI)
• Static HTML (index.html) is used for front page and can be extended.

---

📦 Maven Dependencies

All required dependencies are listed in pom.xml. These include:

• Spring Boot Starter Web
• Spring Boot Starter Thymeleaf
• Lombok (if used)
• Validation and Web MVC

---

📌 Notes

• This is a simulation system, not connected to a real database unless extended.
• You can replace simulation data structures with real database operations as enhancement.
• Make sure to handle validations and edge cases for production.
