Abstract
Data warehouse [2, 4, 5, 6] is an integrated repository derived from multiple source (operational and legacy) databases. The data warehouse is created by either replicating the different source data or transforming them to new representation. This process involves reading, cleaning, aggregating and storing the data in the warehouse model. The software tools are used to access the warehouse for strategic analysis, decision-making, marketing types of applications. It can be used for inventory control of shelf stock in many departmental stores.
