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。
Php 5 introduced true object - oriented support for php applications , at the same time that the php community realized the proliferating set of database - specific extensions was hampering the portability of their database - driven applications by requiring any application aspiring to portable status to implement their own Php 5为php应用程序提供了真正的面向对象支持，同时php社区也认识到专用数据库扩展的增长损害了数据库驱动应用程序的可移植性，因为它要求任何希望具有可移植性的应用程序都必须在数据库专用驱动程序之上实现自己的
