摘要：A data warehouse is a subject-oriented, integrated, time-variant, non-volatile collection of data in support of management's decision making process. Data warehousing is the data management and analysis technology. Data in the data warehouse is preprocessed and presented such that it facilitates the cross functional monitoring and assessment of the overall direction of the organization. Thus, it is the hub for an intelligent management decision support. Successful implementation of a data warehouse requires a high-performance, scale able combination of hardware and software, which can integrate easily with existing systems, so that users can use data warehouse to improve their decision-making. A data warehouse is incomplete until it provides the exploitation tools that enable end users to view analyze and report on data in ways that support their decision-making. Data marts, data mining, data modeling and metadata are some other important concepts attached with data warehousing, the knowledge of which helps to a great extent in data warehouse implementation. Business intelligence data warehouse is the combination of two terms frequently used in the data mining and analysis field. When used together, vendors are trying to emphasize that they offer more services than just data warehousing alone. Because business intelligence can encapsulate a wide variety of services and tools, combining the terms into business intelligence data warehouse reflects that the vendor offers everything an organization needs, including the basics of data warehousing. Many organizations prefer to purchase business intelligence tools and data warehousing as a combined business intelligence data warehouse system in order to increase the efficiency of the integrated system.

In the cleansing stage of the data warehousing process, all inconstancies in the data are determined and taken care of before the data enters the ETL stage. The effectiveness of the data warehouse application intensifies especially when the operational data resides in distributed, non-homogenous systems and replace manual data gathering and reconciliation procedures. Therefore, data warehousing can be useful to not only commercial sectors but also to sectors like government, health care, insurance, manufacturing, finance, distribution, education The goal of a data warehouse application in an organization is to increase the effectiveness of the Decision-making and direction setting process. Data in the data warehouse is preprocessed and presented such that it facilitates the cross functional monitoring and assessment of the overall direction of the organization.
