关于对Oracle数据仓库应用技术研究与实现 　　摘 要：随着科学技术的不断发展，二十一世纪人类已经进入了信息化时代，将计算机、网络、通信以及数据库系统于一身的信息技术成为了社会发展强劲的主要动力。目前，中国化工企业是我国国民经济的主要经济支柱性产业，具有涉及面广、产量规模巨大、管理层面复杂等特点，一直以来都是我国建设的重点行业。由于随着世界能源的日趋紧缺，现阶段，我国的石油化工领域竞争变得越来越激烈，石油化工企业要想在竞争中占有强势地位，加强信息化管理的水平，提升企业管理素质和管理理念，最大程度的取得较好的经济效益是势在必行的发展方向。本文根据Oracle数据仓库开发工具，对石油化工企业管理信息化进行数据仓库的含义、设计原理、建模以及结构优化等技术的研究与探讨，供各位朋友鉴赏。 　　关键词：Oracle数据仓库；定义；设计原理；逻辑设计思路；建模；优化 　　中图分类号：TP274+.2 文献标识码：A DoI: 10.3969/j.issn.1003-6970.2012.05.041 　　Research and Realization on the Oracle Data Warehouse Application Technology 　　SU Le-ming 　　( PetroChina Jidong Oilfield Archives Information Center, Hebei, Tangshan 063000) 　　【Abstract】With the development of science and technology, mankind in the twenty-first Century has entered the information era, computer, network, communication and database system in an information technology has become the main motive force of social development is strong. at present, china chemical enterprises in china’s national economy is the main economy pillar industries, has involved extensive, production scale, management level of large complex wait for a characteristic, has been the emphases of our country’s construction industry. For as the world’s energy shortage, at this stage, China’s petrochemical industry competition is becoming increasingly fierce, petroleum and chemical enterprise wants to be in competition occupies a position of strength, strengthen information management, to improve enterprise management quality and management philosophy, the greatest degree of good economic benefit is to be imperative development direction. In this paper, according to the oracle data warehouse development tool, the petrochemical enterprise information management data warehouse meaning, design principle, modeling and optimization of structure of research and Discussion on the technology of appreciation, for your friends. 　　【Key words】the oracle data warehouse; Definition; Principle of design; Logic design; Modeling; optimization 　　 0 引 言
