This project is a desktop application built with Python and PyQt5 that interacts with an MSSQL database to manage a library system.

Detailed report availabe in Report.pdf

## Key Features

* **User Authentication:**

    * Manager and Customer login pages with secure password handling (demonstrates data security awareness).

    * Customer registration functionality.

* **Book Management (Manager Side):**

    * **Find Books:** Search for books by name, genre, author, and publication year.

    * **Add Book:**  Functionality to add new books to the database.

    * **Edit Book:**  Modify existing book information.

    * **View Current Borrowers:**  See which customers currently have a specific book borrowed.

* **Customer Operations (Customer Side):**

    * **Find Books:** Search for available books to borrow.

    * **Borrow Books:**  Borrow books, updating book availability and recording borrowing history.

    * **Return Books:**  Return borrowed books, updating availability and recording return dates.

    * **View Borrowed Books:** See a list of currently borrowed books.

    * **Borrow History:**  View a history of all books borrowed by a customer.

* **Customer Management (Manager Side):**

    * **Find Customers:** Search for customers based on various criteria (ID, name, contact info, etc.).

    * **View Customer Book History:** (Through "Find Customers" and then "Books" button) - See borrowing history for individual customers.

* **Manager Management (Manager Side):**

    * **Add Manager:** Functionality to add new manager accounts.

* **Data Display:**  Uses PyQt5 `QTableWidget` to display data from the database in a structured and sortable table format.

* **Error Handling:**  Includes error handling and user feedback through message boxes (e.g., login status, input validation).

## Tools Used

* **Python:** Core programming language for the application logic and GUI.

* **PyQt5:**  Python library for creating the graphical user interface (GUI).

* **SQLAlchemy:** Python ORM (Object-Relational Mapper) for interacting with the MSSQL database. Provides a Pythonic way to write SQL queries and manage database operations.

* **MSSQL Server:** Relational database management system used to store library data.

* **pyodbc:** Python library for connecting to ODBC databases (used for MSSQL connectivity).

## Database Setup (MSSQL)

Before you run the Library Book Management System, you **must** set variables that tell the application how to connect to your MSSQL database using **Trusted Connection (Windows Authentication)**.

You need to set the following variables in the .env file and **save** the file:

*   **`DB_SERVER`**: The address or hostname of your MSSQL Server. This could be:

    *   `localhost` or `127.0.0.1` if your MSSQL Server is running on your local machine.

    *   The computer name of your MSSQL Server if it's on your local network (e.g., `DESKTOP-SERVER`).

    *   The IP address or hostname of your MSSQL Server if it's running remotely or in the cloud.

*   **`DB_NAME`**: The name of your MSSQL database (e.g., `LibraryDB`).

* **Ensure you have access to an MSSQL Server.**

* **Create an empty database** that you will use for this application. Note down the database name.

* **Run the provided `database_schema.sql` script** against your newly created database to create the necessary tables. This script is located in the root of the repository. You can use a tool like SQL Server Management Studio to execute the script.

* **Install Python Dependencies:**

    ```bash

    pip install -r requirements.txt

    ```
