SQL Server 2025 Standard VS Enterprise

There is some difference between SQL Server 2025 Standard and Enterprise edition such as;

CAL Fundamental

It Provides the option to license users and/or devices, with low-cost access to incremental SQL Server deployments such as;

Each server running SQL Server software requires a server license.
Each user and/or device accessing a licensed SQL Server requires a SQL Server CAL that is the same version or newer - for example, to access a SQL Server 2017 Standard Edition server, a user would need a SQL Server 2017, 2019, 2022 or 2025 CAL.
Each SQL Server CAL allows access to multiple licensed SQL Servers, including Standard Edition and legacy Business Intelligence and Enterprise Edition Servers.
