Microsoft SQL Server

Enterprise relational database for transactional workloads, analytics, and hybrid cloud.

Overview

Microsoft SQL Server 2025 is an enterprise-grade relational database platform designed for mission-critical workloads. It combines best-in-class security and performance with built-in AI capabilities, allowing organizations to accelerate AI innovation using their existing data through native vector support, semantic search, and integrated AI model deployment.

The platform offers multiple editions to suit different needs: Enterprise for Tier 1 workloads, Standard for mid-tier applications, Developer for non-production environments (free), and Express for small applications (free). SQL Server integrates seamlessly with Azure services, Microsoft Fabric, and Azure Arc, enabling zero-ETL analytics, cloud agility, and simplified licensing through pay-as-you-go models.

Developers benefit from native JSON support, REST interface connectivity, regular expression querying, and integration with popular frameworks like LangChain, Semantic Kernel, and Entity Framework Core. The platform emphasizes security through Microsoft Entra authentication, enhanced business continuity features, and centralized management across on-premises and multicloud environments.
