商业智能(BI)的产生与发展

0

商业智能(Business Intelligence,简称:BI),又称商业智慧或商务智能,指用现代数据仓库技术、线上分析处理技术、数据挖掘和数据展现技术进行数据分析以实现商业价值。

国内BI系统提供奥为软件曾发表观点表示,把商业智能(BI)看成是一种解决方案应该比较恰当。商业智能(BI)的关键是从许多来自不同的企业运作系统的数据中提取出有用的数据并进行清理。

以保证数据的正确性,然后经过ETL过程,合并到一个企业级的数据仓库里,从而得到企业数据的一个全局视图,在此基础上利用合适的查询和分析工具、数据挖掘工具、OLAP工具等对其进行分析和处理(这时信息变为辅助决策的知识),最后将知识呈现给管理者,为管理者的决策过程提供支持。商业智能(BI)作为一个工具,是用来处理企业中现有数据,并将其转换成知识、分析和结论,辅助业务或者决策者做出正确且明智的决定。是帮助企业更好地利用数据提高决策质量的技术,包含了从数据仓库到分析型系统等。

商业智能(BI)20世纪90年代末首先在国外企业界出现的一个术语,其代表为提高企业运营性能而采用的一系列方法、技术和软件。它把先进的信息技术应用到整个企业,不仅为企业提供信息获取能力,而且通过对信息的开发,将其转变为企业的竞争优势,也有人称之为混沌世界中的智能。

商业智能(BI)的概念经由Howard Dresner(1989)的通俗化而被人们广泛了解。当时将商业智能(BI)定义为一类由数据仓库(或数据集市)、查询报表、数据分析、数据挖掘、数据备份和恢复等部分组成的、以帮助企业决策为目的技术及其应用。

因此,越来越多的企业提出他们对BI的需求,把BI作为一种帮助企业达到经营目标的一种有效手段。

目前,商业智能(BI)通常被理解为将企业中现有的数据转化为知识,帮助企业做出明智的业务经营决策的工具。这里所谈的数据包括来自企业业务系统的订单、库存、交易账目、客户和供应商资料及来自企业所处行业和竞争对手的数据,以及来自企业所处的其他外部环境中的各种数据。商业智能(BI)能够辅助的业务经营决策既可以是作业层的,也可以是管理层和策略层的决策。

为了将数据转化为知识,需要利用数据仓库、线上分析处理(OLAP)工具和数据挖掘等技术。因此,从技术层面上讲,商业智能(BI)不是什么新技术,它只是ETL(抽取(Extraction)、转换(Transformation)和装载(Load))、数据仓库、OLAP、数据挖掘、数据展现等技术的综合运用。
