HOW UP-TO-DATE SHOULD DATA WAREHOUSE INFORMATION BE?

Information timeliness is a must in a data warehouse-old and obsolete information leads to poor decision making. Below is a list of decision-making processes that people go through for different business environments.

For each, specify whether the information in the data warehouse should be updated monthly, weekly, daily, or by the minute.

Be prepared to justify your decision. To adjust classes sizes in a university registration environment. To alert people to changes in weather conditions.

To predict scores of professional football games. To adjust radio advertisements in light of demographic changes. To monitor the success of a new product line in the clothing retail industry. To adjust production levels of food in a cafeteria. To switch jobs to various printers in a network. To adjust CD rates in a bank. To adjust forecasted demands of tires in an auto parts store.
