Which SQL Server edition measure is NOT included when checking for potential savings on licenses?

When evaluating potential savings on SQL Server licenses, SQL Server Express is not included in the calculations for savings measures. This is largely because SQL Server Express is a free version of SQL Server, designed for smaller-scale applications and development purposes. It does not require a paid license, and therefore, there are no associated savings to consider when discussing licensing costs.

In contrast, SQL Server Enterprise, Standard, and Developer editions involve various licensing models and costs that organizations must account for. These editions have different features, capabilities, and pricing structures that impact their cost, making them relevant in discussions about potential savings from license management or optimization. Hence, when assessing potential savings, only the editions that incur licensing fees – which are the Enterprise, Standard, and Developer editions – are relevant, while Express, being free, does not factor into this analysis.
