Managing a business in today’s dynamic world has never been easy. The challenge is to do more with less and to make better decisions than competitors. Having constant access to current, actionable information has become need of time. The best decisions are made when all the relevant data is available and the best possible source for that data is a well-designed data warehouse.
A data warehouse is a database that is specifically designed to produce information for reporting and analysis. “Reporting and analysis” can be anything from listings of sales figures, to hi-tech dashboards, email alerts, ad-hoc reporting and drill-up, drill-down analytics. Data is extracted periodically from the applications that support business processes and copied onto special dedicated computers. There it can be validated, reformatted, reorganized, summarized, restructured, and supplemented with data from other sources. The resulting data warehouse becomes the main source of information for report generation, analysis, and presentation through ad-hoc reports and dashboards.
