在建设一个综合信息处理系统过程中,有集中式和分布式(局域网)两种常见的网络结构模式。两种构网方式各有优缺点,应从实际出发综合考虑、灵活选择,实现资源面向具体应用问题的最佳配置。本文结合笔者从事工商银行系统MIS应用开发的实践,讨论一个基于网络互连技术,以银行综合信息处理为目标,以数据库为主环境的集中/分布式系统网络结构及实现技术。一、系统的物理构成与软件开发平台整个信息处理系统的核心由3台ERGO486微机组成3个子系统。(1)数据采集处理机采用ERG0486/20作为数据采集部分的处理机,硬件配置:3MB内存,200MB硬盘。通过8串接口卡、MODEM和拨号电话线路与分布在各地的下一级银行分支机构的同类型或不同类型通讯节点机相互连接成网络。
In the process of building an integrated information processing system, there are two common network structure modes: centralized and distributed (LAN). Two kinds of network have their own advantages and disadvantages, should be considered from the actual situation, flexible choice, to achieve the optimal allocation of resources for application-specific issues. This paper combines the author’s practice of MIS application development in ICBC system, and discusses a centralized / distributed system network structure and implementation technology based on network interconnection technology, integrated bank information processing and database-based environment. First, the system’s physical composition and software development platform The core of the entire information processing system consists of three ERGO486 microcomputer composed of three subsystems. (1) Data Acquisition Processor ERG0486 / 20 is used as the data acquisition part of the processor, the hardware configuration: 3MB memory, 200MB hard drive. Through 8 series of interface cards, MODEM and dial-up telephone lines are distributed with the branches of the same type or different types of communication node machines of the next bank branches connected to each other into a network.
