According to the concrete situations of Wushan seismostation, a data management system has been successfully accomplished by using Fo-chase + 2. 10 in CCDOS environment. The system is mainly used to manage data and automatically generate all kinds of tables. The procedure is designed adopting top-down and stepwise refinement way. All of the modules have pull-down menu and man-machine interfaces are very friendly. In the procedure, maximum failure tolerance is adopted and its performance is very good. The practical run over a year has shown that the system perfectly satisfies the needs of day-to-day work of the Wushan seismostation.
