Build AI Applications Using Existing Business Data
Microsoft SQL Server 2025 brings AI-oriented data operations directly into the database engine. Developers can store vector embeddings, calculate vector similarity, and combine semantic and keyword-based searches without moving core business data to a separate database platform.
 
These capabilities support applications such as intelligent search engines, recommendation systems, document discovery tools, and retrieval-augmented generation solutions. Familiar T-SQL tools help development teams introduce AI features while continuing to use their existing database skills and workflows. 
 
Modern Tools for Application Development
Native JSON support makes it easier to store, index, query, and exchange semi-structured information. External REST endpoint invocation allows database applications to communicate with compatible web services, while regular expression functions provide flexible tools for finding, validating, replacing, and transforming text.
 
SQL Server 2025 also extends the modern T-SQL surface area, helping developers create data-intensive applications for on-premises, cloud, Linux, Windows, and container-based environments. 
 
Improved Performance and Workload Control
Intelligent query processing features help SQL Server adapt execution strategies to real workload conditions. Optional parameter plan optimization can generate different execution plans for different parameter values, while cardinality estimation feedback learns from previous executions to improve future queries.
 
Optimized locking is designed to increase concurrency in transactional applications. Query Store improvements, resource governance, and tools for blocking known problematic queries give administrators greater control over database performance and resource usage.
 
Enterprise Security, Availability, and Hybrid Integration
Microsoft SQL Server 2025 supports Microsoft Entra ID authentication, managed identities, encryption technologies, auditing, and established SQL Server security controls. These features help organizations manage access consistently across local and cloud-connected environments.
 
Enhancements to Always On availability groups strengthen business continuity and database availability. Microsoft Fabric mirroring enables near-real-time access to operational data for analytics, while Azure Arc supports centralized governance and management across hybrid infrastructure.
