An open-source natural language to SQL data agent has been developed using LangChain and LangGraph, leveraging LangChain’s SQLDatabase utility for efficient database access. This tool supports various databases, including PostgreSQL, Azure SQL, Cosmos DB, Databricks SQL, and BigQuery, and offers Azure AD authentication for Azure-native databases. Users can ask questions in plain English, which are processed through an intent detection agent to generate and safely execute SQL queries, returning results in a natural language format. The system is designed as a YAML-driven, multi-agent framework with an Agent-to-Agent server for seamless integration and communication between agents. This matters because it simplifies data querying for users without SQL expertise, enhancing accessibility and efficiency in data management.
