In order to manage and handle the large amount of data which are needed and produced during the design of accelerator cavity , by applying the database technology , we design and establish a special database management system prototype for accelerator rf cavity design , called fisfdbase . we also basically implement a framework of the system prototype 为了利用数据库技术来管理和处理加速器腔设计时所需要的和产生的大量数据,论文设计和建立了一个加速器高频腔设计专用数据库管理系统原型fishbase ,并初步实现了该系统原型的框架。
