Microsoft SQL Server is classified as which type of DBMS?

Microsoft SQL Server is classified as a database management system (DBMS) that operates effectively on midrange computers. This classification acknowledges its ability to handle significant data volumes and support multi-user environments effectively, which is characteristic of midrange systems. SQL Server is designed for enterprise-level solutions, allowing for robust transaction processing, data analysis, and business intelligence, making it suitable for applications and workloads that require high availability and scalability.

In contrast to other options, a DBMS for small handheld computing devices would not adequately represent the capabilities of SQL Server, as it is designed to manage much larger datasets and complex queries. An Internet DBMS usually focuses on web-related databases which are more specialized, while a desktop relational DBMS would imply a limit in functionality and scale that SQL Server surpasses. This makes the classification as a DBMS for midrange computers particularly fitting, as it encompasses both the strength and flexibility that SQL Server offers in enterprise applications.
