systems application architecture

With the wide application of internet / intranet technology and rapid development of the information technology . management information system models have evolved from m / t ( mainframe / terminal ) model to b / s model , by c / s model , correspondingly , the system architecture has developed from single - tier structure to 3 - tier , by 2 - tier . this thesis has narrated the development course of the platform mode of the management information system , introduced briefly the basic conception of component technology and relevant standard . analysed synthetically com / dcom / com + ' s technology to microsoft , stated in detail the basic principle of the artificial nerve network and realization of bp algorithm and flow , introduced bp algorithm improved in setting up and predicting the applications of model further
随着internet intranet技术的广泛应用及信息技术的迅速发展，管理信息系统开发模式在沿着主机终端模式到c s模式再到b s模式这条道路上前进，相应地系统应用体系结构也由单层结构发展到二层结构再到三层结构。本文叙述了管理信息系统平台模式的演变过程，简要地介绍了组件技术的基本概念和相关标准，并对微软的com dcom com +技术进行了综合分析，详细地说明了人工神经网络的基本原理和bp算法的实现和流程，进一步介绍了改进的bp算法在建立预测模型中的应用。
