    <h3>Why use databases?</h3>
    <ul>
        <li>Store large amounts of data while using little space.</li>
        <li>Easy to add, remove, and search for information.</li>
        <li>High security features like <a href="https://cloud.google.com/learn/what-is-a-relational-database" target="_blank">relational database</a> prevent from inconsistent data as data in multiple tables is related and must be handled properly.</li>
        <li>Easy to integrate into other programs and use the data for purposes like data analysis.</li>
    </ul>

        <li>Hospitals - store details about patients like history of their health issues.</li>
