Dataherald provides a natural language to SQL (NL-to-SQL) engine that enables users to query structured databases using plain English instead of SQL code. The platform works by connecting to various data warehouses including Postgres, BigQuery, Databricks, and Snowflake, and employs two LangChain agents - a RAG-only agent for scenarios with limited sample data and an advanced agent that uses fine-tuned language models. The technology extracts essential database information such as table schema, categorical values, and descriptions, while incorporating business context and metadata to generate accurate SQL queries. The platform validates query accuracy through SQL execution and error recovery tools.
