Remote access to a SQL server is important because it allows users to access the server from anywhere, at any time. This enables remote workers to access the data they need when they need it, even if they are not physically in the same location as the server. It also allows IT admins to access the server from any location to provide support and troubleshoot any issues, without having to be physically present. Remote access also increases security, as admins can monitor the server from any location and can quickly react to any threats or suspicious activities.
