About Microsoft Azure SQL Database
Microsoft Azure SQL Database is a highly scalable, intelligent, managed relational database service built for the cloud. It offers the latest stable version of the Microsoft SQL Server engine, handling most database management functions like upgrading, patching, backups, and monitoring without user involvement. The service features multiple deployment models, including serverless compute that auto-scales based on workload and Hyperscale for very large databases up to 100 TB. It deeply integrates with the Azure ecosystem, supporting Azure OpenAI for building RAG applications with vector search, and near real-time data replication into Microsoft Fabric for analytics. It also includes a Data API builder to generate REST and GraphQL APIs directly from database objects, simplifying development.
