Google has launched Mangle, a new programming language built on Datalog specifically designed for deductive database programming. Mangle offers powerful features including aggregation support, function calls within queries, optional type checking, recursive rules, and the ability to work across multiple databases. Unlike SQL or Python, Mangle is declarative and allows complex data reasoning without extensive code. It's particularly useful for data integration, graph analysis, ontology reasoning, and complex data analysis across industries like finance and AI. The language is available as an open-source project on GitHub with documentation and examples for developers to get started.
