Server and CAL Licensing Server

When licensing SQL Server under the server and CAL model, you purchase a server license for the server and client access licenses (CALs) for each device (Device CALs) and/or user (User CALs) accessing or using the services or functionality of SQL Server. A CAL is not software; it is a legal document granting access. The server and CAL model is appropriate when you can count your users or devices, or when the number of users and devices is low enough that the cost is lower than licensing by processor.
