<h2>What are CRUD operations?</h2>
<p>CRUD is an acronym representing the four basic functions of persisted storage (most commonly a database).</p>
<ul>
<li>
<strong>Create</strong> - In SQL, this translates to an <code>INSERT</code> statement. This is how data is initially loaded to storage.
</li>
<li>
<strong>Read</strong> - In SQL, this translates to a <code>SELECT</code> statement. This is how data is retrieved and ultimated consumed by an application.
</li>
<li>
<strong>Update</strong> - In SQL, this translates to an <code>UPDATE</code> statement. This is how data is modified in storage.
</li>
<li>
<strong>Delete</strong> - In SQL, this translates to a <code>DELETE</code> statement. This is how data is hard-deleted (permanently removed) from storage. This should not be confused with a soft-delete which may be implemented as an update to an "Active" or "Enabled" property.
</li>
</ul>
