This study introduced the development history and current research status of large language model (LLM), data Quartz Accessories query robot (DQR).Meanwhile, through empirical analyses, the practical application effect of LLM-based DQR and its role in dealing with the complex tasks of medical data querying and analysis in the field of digital medicine was explored, and it was confirmed that LLM-based DQR could provide non-technical people with an intuitive and convenient tool to significantly improve the querying efficiency and analysis capability of medical data.In addition, this paper Stepping Stones discusses the limitations and potential of future development of LLM and DQR techniques in current applications, providing reference for further research and applications.
