随着数据仓库技术的发展,在线分析、数据挖掘已渐渐获得了券商的青睐,但数据仓库在证券业中却鲜有成功的案例,大部分券商对数据仓库也都持观望的态度,对数据仓库的应用仅限于研究阶段。那么究竟数据仓库的“行”在何处:它可以为我们带来什么?为什么“不行”:它的应用为什么不能达到其预期的效果?怎样才能使数据仓库从“不行”的模式转到到“行”的模式?本文试对此进行探讨,并认为数据的集中统一是数据仓库应用的基础;确立合理的数据模型是数据仓库应用的核心;高效的应用系统是数据仓库应用的动力;良好的外部环境是数据仓库成功应用的外部保障。
With the development of data warehousing technology, online analysis and data mining have gradually gained the favor of brokers. However, data warehousing has few successful cases in the securities industry. Most brokers also hold a wait-and-see attitude towards data warehousing. The use of warehouses is limited to the research phase. So what exactly is the “line” of the data warehouse: what can it bring to us? Why “no”: why its application does not achieve its intended effect? And how can the data warehouse be shifted from the “no” mode to This paper tries to explore this and thinks that the centralization and unification of data is the basis of data warehouse application. Establishing reasonable data model is the core of data warehouse application. Efficient application system is the power of data warehouse application. The external environment is an external guarantee for successful application of data warehouse.
