国家烟草专卖局为适应行业发展的需要,实现烟草行业工商数据的集成,构建一个基于行业现有信息网络基础的烟草行业卷烟生产经营决策管理系统。烟草行业卷烟生产经营决策管理系统分为两个子系统:数码跟踪子系统和工商数据采集子系统,其中工商数据采集子系统为这次的重点,负责采集工商企业的内部生产经营数据。工商数据采集子系统按照实施对象的不同又分为工业数据采集子系统和商业数据采集子系统,其中工业数据采集子系统为本文研究的对象。由于要跨数据库抽取数据,难点在于通用的数采程序怎样与各种数据库建立连接。同时为照顾到企业的各种情况,还必须设计其他抽取方法来抽取数据。数据抽取完成后还必须设计数据存储和上传方法。将全面研究整个数采系统的设计并给出实现方法。
In order to meet the needs of the development of the industry, the State Tobacco Monopoly Administration realized the integration of business data in the tobacco industry and established a cigarette production and operation decision-making management system based on the existing information network in the industry. Tobacco industry cigarette production and operation decision-making management system is divided into two subsystems: digital tracking subsystem and business data acquisition subsystem, including business data acquisition subsystem for this focus, responsible for collecting business production and operation of internal data. The industrial and commercial data collection subsystem is divided into industrial data acquisition subsystem and commercial data acquisition subsystem according to different implementation objects. The industrial data acquisition subsystem is the object of this paper. Because of the data to be extracted across the database, the difficulty lies in the common data mining procedures how to establish a connection with a variety of databases. At the same time to take care of the business situation, but also must design other extraction methods to extract data. Data extraction must also be designed after the data storage and upload methods. We will thoroughly study the design of the whole system and give the implementation method.
