Design of Database System of HIRFL-CSR Beam Line

This paper introduces the database design and optimization for the power supply system of Lanzhou Heavy Ion Accelerator CSR (HIRFL-CSR) beam line. Based on HIFEL-CSR main Oracle database system, the interface was designed to read parameters of the power supply while achieving real-time monitoring. A new database system to store the history data of power supplies was established at the same time, and it realized the data exchange between Oracle database system and Access database system. Meanwhile, the interface was designed conveniently for printing and query parameters.
