What is Microsoft SQL Server?

Microsoft SQL Server is a complete relational database management system (RDBMS) that goes far beyond simply storing and retrieving data. SQL Server is a comprehensive data platform that combines database management, business intelligence, data analysis, reporting, and integration services into a single, cohesive platform.

In everyday business operations, SQL Server is the database behind nearly every Microsoft-based business application. ERP systems such as Microsoft Dynamics, CRM solutions, SharePoint, Exchange Server, and countless industry-specific applications rely on SQL Server as their database foundation. Anyone operating a professional Microsoft-based IT infrastructure will, in most cases, find SQL Server indispensable.

SQL Server Licensing Models – What Do I Need to Know?

SQL Server is licensed according to two basic models, which differ significantly in structure and cost-effectiveness depending on the use case.

Server + CAL Model – With the Server + CAL model, you purchase a server license and, in addition, an SQL Server CAL for each user or device that accesses the SQL Server. This model is cost-effective when the number of users is known, manageable, and stable. When there are only a few users accessing a high-performance database, the Server + CAL model is generally more cost-effective than the Core model.

Core model – In the Core model, SQL Server is licensed based on the number of physical processor cores on which the server runs. At least four Core licenses must be purchased for each physical CPU. The Core model does not require CALs—an unlimited number of users and devices may access the SQL Server. This model is cost-effective when many or an unknown number of users access the database, such as in public web applications or large enterprise environments.

Choosing the right licensing model depends on your specific situation. If you’re unsure, we’re happy to help—just get in touch.

SQL Server Editions at a Glance

SQL Server is available in several editions that differ in their feature sets and use cases:

• SQL Server Standard
• The most popular edition for small and medium-sized businesses and departmental applications. Standard offers complete database functionality for most business needs—including Always On Availability Groups for high availability (limited), replication, Reporting Services, and Integration Services. For companies that need a powerful, full-featured database platform without the advanced enterprise features, Standard is the more cost-effective choice.
• SQL Server Enterprise
• The most powerful edition for mission-critical applications with the highest demands on performance, high availability, and scalability. Enterprise offers unlimited virtualization, full Always On Availability Groups with up to eight secondary replicas, In-Memory OLTP for maximum transaction performance, advanced compression, and full business intelligence capabilities. For large enterprises and mission-critical workloads, Enterprise is the essential choice.
• SQL Server Developer
• The free edition for developers—functionally identical to Enterprise, but licensed exclusively for development and testing, not for production environments.
• SQL Server Express
• The free entry-level edition with limited functionality and a database size capped at 10 GB. For small applications, single-user databases, and educational applications.

Frequently Asked Questions About Microsoft SQL Server

What is the difference between SQL Server Standard and Enterprise?

SQL Server Standard offers full database functionality for most business needs at a cost-effective price. SQL Server Enterprise adds unlimited virtualization, full Always On Availability Groups, In-Memory OLTP, and advanced business intelligence features. For mission-critical workloads with the highest demands on performance and high availability, Enterprise is the necessary choice.

Server+CAL or Core—which model is better for me?

Server+CAL is more cost-effective when a small number of known users access the database. The Core model is more cost-effective when many users—or an unknown number of users—access the database. As a rule of thumb: For up to about 25 users, Server+CAL is often cheaper; for larger numbers of users, Core becomes more cost-effective. We’d be happy to advise you on your decision.

Do I still need CALs with the Core model?

No. The Core licensing model does not require any additional CALs—an unlimited number of users and devices can access the SQL Server.

Can I run SQL Server on virtual machines?

Yes. SQL Server can be run on both physical and virtual machines. The licensing rules for virtual environments are complex—especially for SQL Server Enterprise with unlimited virtualization. We’d be happy to advise you on the specific licensing requirements for your virtualization environment.

How quickly will I receive my license key?

Immediately after purchase—your activation key will be sent automatically via email. Activation via the official Microsoft servers then takes only a few minutes.
