Azure SQL Developer: instant REST + GraphQL API with Data API Builder

Generate a full REST and GraphQL API over the local Azure SQL Developer (Private Preview) with no application code, using Data API Builder (DAB) - Microsoft's first-party open-source engine. You describe tables as entities in dab-config.json; DAB serves them. DAB connects over the normal TDS protocol with a plain connection string, so no change tracking or special engine feature is needed.
