摘　　要：The control system of SSRF(Shanghai Synchrotron Radiation Facility)is based on EPICS(Experimental Physics and Industrial Control System).Operation data storage for synchrotron radiation facility is important for its status monitoring and analysis.At SSRF,operation data used to be index files recorded by traditional EPICS Channel Archiver.Nevertheless,index files are not suitable for long-term maintenance and difficult for data analysis.Now,RDB Channel Archiver and MySQL are used for SSRF beamline operation data archiving,so as to promote the data storage reliability and usability.By applying a new uploading mechanism to RDB Channel Archiver.its writing performance is improved.A web-based GUI(Graphics User Interface)is also developed to make it easier to access database.The control system of SSRF （Shanghai Synchrotron Radiation Facility） is based on EPICS （Experimental Physics and Industrial Control System）.
