Information from the data warehouse was delivered to this group of users in a client/server environment. But today’s data warehouses are no longer confined to a select group of internal users. Under present conditions, corporations need to increase the productivity of all the members in the corporation’s value chain. Useful information the corporate data warehouse must be provided not only to the employees but also to customers, suppliers and all other business partners. So today’s business climate, you need to open your data warehouse to the entire community of users in the value chain, perhaps also to the general public. This is a tall order. How can you accomplish this requirement to serve information to thousands of users in 24*7 mode? How can you do this without incurring exorbitant costs for information delivery? The Internet along with Web technology is the answer. The web will be your primary information delivery mechanism. When you bring your data warehouse to the Web, from the point of view of the users, the key requirements are: self-service data access, interactive analysis, high data quality, high availability and performance, zero-administration client (thin client technology such as Java applets), tight security and unified metadata.enData warehouseWebBanking systemData qualityThesis
