Its main purpose is to provide a coherent picture of the business at a point in time. Using various Data Warehousing toolsets, users are able to run online queries and ‘mine” their data.
Many successful companies have been investing large sums of money in business intelligence and data warehousing tools and technologies. They believe that up-to-date, accurate and integrated information about their supply chain, products and customers are critical for their very survival.
