Abstract: The MingantU SpEctral Radioheliograph (MUSER) has entered the stage of routine observation and will generate massive observation data. How to effectively manage and query massive observation data has become a critical and urgent problem for the MUSER. A negative database management system for the MUSER is used to solve the mentioned problem. In this paper, we have introduced the design and implementation of the MUSER negative database interfaces in detail. Meanwhile, the system can not only solve the problem of the MUSER effectively, but also provide a valuable reference for the next-generation telescope system.
