IMPORTANT NOTE:  A minimum of 5 CALs is required as well as a server license

Client Access Licenses (CALs) are required for each device or user that accesses the features and services of Microsoft SQL. User CALs are likely to be more cost effective than Device CALs if there are multiple devices per user (for example, a user has a laptop and handheld computer accessing SQL Server)

SQL Server 2005 is designed to help enterprises address these challenges. This next-generation data management and analysis solution delivers increased security, scalability, and availability to enterprise data and analytical applications, while making them easier to build, deploy, and manage.
