摘要
数据转移是联结事务型数据环境和决策支持环境的纽带 ,对这一技术的研究有着重要意义。从讨论数据转移面临的问题开始 ,逐步就数据抽取、数据净化、数据转换和数据集成等数据转移的重要环节进行深入的探讨 ,给出若干数据转移问题的解决方法和实现实例。
Data transfer is the link between the transaction data environment and decision-making supporting environment. Problems arising from data transfer are discussed. Main steps in data transfer like data extraction, data cleansing, data transformation and data integration are detailed. Some measures are presented to solve these problems. Finally an example of data transfer is given in this paper.
