# Database Management Tool

This Python application manages a SQLite database containing student, professor, subject, and grade data for a school. It provides functions to create, populate, query, and interact with the database.

## Features

- **Database creation and table management:**

    - Creates SQLite database file `db.sqlite3` with the following tables:

        - `groups`

        - `students`

        - `professors`

        - `subjects`

        - `grades`

    - Establishes appropriate foreign key relationships between tables.

    - Inserts randomly generated student, professor, subject, and grade data into the tables.

- **Data retrieval and display:**

    - Retrieves and displays data from all tables.

- **SQL script execution:**

    - Executes all SQL files located in the `SQL` subdirectory, allowing for more complex queries and analysis.

## Usage
