Data API builder documentation
Data API builder (DAB) provides a REST API over a database. It also provides a GraphQL API. It supports not just SQL Server, but Azure SQL Database, Azure Cosmos DB, PostgreSQL, MySQL, and SQL Data Warehouse. DAB runs in any cloud or on-prem, and it is open source and free to use. It's secure, feature-rich, and a foundational component of Microsoft Fabric—which is another way of saying it’s high-performance and capable of handling massive data operations.
