Microsoft has announced four editions and pricing plans for SQL Server 2005. The company will offer three license plans for SQL Server 2005: processor licenses, server plus device Client Access Licenses (CALs), and server plus user CALs. Processor licenses require a separate license for each processor running SQL Server. You'll pay for a fixed server license plus additional CAL licenses for each device or user that connects to SQL Server under the server plus device CAL and server plus user CAL, respectively. Here are the four editions that Microsoft will release for SQL Server 2005. Note that all higher editions include the same functionality as the editions below it.
