Data warehouses shrink the length of time it takes between a business event's occurrence and executive alert. For example, in many
hospitals, management reports are printed once a month - about a week after the end of each month. Thus, the June
management reports are delivered during the first week in July. Using a warehouse, those same reports are available on a daily basis. Given this data delivery time compression, business decision makers can exploit opportunities that they would otherwise miss.
