      • Navigate to the Downloads section.
      • Choose the MySQL Community Server.
      • Select the appropriate version for your operating system.
    2. Installation:

      • Configure the server settings as needed during the setup.
      • Set up a root password.
      • Optionally install MySQL Workbench for a GUI interface.

    SQL Server

    1. Download SQL Server:

      • Visit the official Microsoft SQL Server website.
      • Choose the edition you need (Express is a free version).
      • Download the installer.
    2. Installation:

      • Run the setup file.
      • Follow the installation wizard, selecting your desired features.
      • Configure the instance and server settings.
      • Set authentication mode and add SQL Server administrators.

    1. Download SQLite:

      • Go to the SQLite official website (https://www.sqlite.org/).
      • Download the precompiled binaries for your operating system.
    2. Installation:

      • SQLite doesn’t require a traditional installation process.
      • Extract the files and use the SQLite command-line tool or integrate it into your application.

    Code Example (SQLite in Python)

    Here's a basic example of how to use SQLite in Python:

    import sqlite3
    # Connect to SQLite database (or create if it doesn't exist)
    conn = sqlite3.connect('example.db')
    # Create a cursor object using the cursor() method
    cursor = conn.cursor()
    # Create table
    cursor.execute('''CREATE TABLE IF NOT EXISTS stocks (date text, trans text, symbol text, qty real, price real)''')
    # Insert a row of data
    cursor.execute("INSERT INTO stocks VALUES ('2022-01-01','BUY','AAPL',100,35.14)")
    # Save (commit) the changes
    # Close the connection

    This is a basic guide, and the exact steps may vary based on your system and the specific version of the SQL software. Always refer to the official documentation for the most accurate and detailed instructions.
