数据库从出现至今,经历了多个发展阶段。在数据库自身的架构上,已经淘汰了早期不能满足需求不完善的文件系统结构或者单机结构,现在最经常使用的是C/S模式架构和B/S模式架构。当然,它们也有着自己的优点和缺点,C/S模式的长处在于访问速度、安全性能和个性化突出,而B/S模式在客户端方面的简单性是其压倒性优势。介于各有优缺点的客观情况,很多单位或者个人在数据库管理系统的选择上,只能鱼和熊掌不可兼得,牺牲一部分利益而选择它们其中之一。本文研究的对象主要是将C/S模式和B/S模式相结合。在它们弥补对方缺点的同时发挥自己的优点,使得两种模式的数据库结合后,有着高度的安全性和并发性,并使数据库的性能得以优化。

There are several stages of development since database appears.On the structure of the database,it has eliminated file system structure and stand-alone structure which can not meet the needs and are very imperfect.Now instead,the most frequently used structures are the C/S mode structure and B/S mode architecture.Of course,they also have their own advantages and disadvantages,C/S model＇s strength lies in speed of access,security,performance and individuality,while the B/S mode on the client＇s simplicity is its overwhelming advantage.Because of the advantages and disadvantages of them,when many units or individuals make their decisions,they have to choice one of them and give up the other. The main object of this paper is the combination of C/S mode and B/S mode.They make up for their shortcomings in while play their strengths,making the combined database of two modes has a very high degree of security and concurrency,and thus the database performance can be optimized.
