AI Technical Summary

Technical Problem

Current AI-generated SQL suffers from low accuracy, lacks semantic enhancement and business constraint knowledge, resulting in inaccurate or non-compliant SQL statements, high data security risks, unauditable reports, poor interactivity, weak data source adaptability, and a lack of structured semantic models.

Method used

The DLF-based AI-trusted data query device generates OFD electronic certificates through a data configuration module, a data table parsing module, a semantic enhancement module, an interactive SQL generation module, a syntax pre-validation module, and a data execution module, ensuring the traceability and security of each link and building a trusted traceability chain.

Benefits of technology

It achieves accuracy and security in AI-generated SQL, ensuring that the generated SQL conforms to business logic, eliminating data security risks, providing a reliable report verification mechanism, improving data source adaptability and interactivity, and forming a reliable traceability chain throughout the entire lifecycle.
