Semi-Star Modeling Schema for Managing Data Warehouse Consistency

Decision-making has always been a complicated process due to reason of ever increasing number of alternatives; the relationships between the variables involved are complex, and frequent changes. The supporting systems to decision-making include data warehouse and data mining. Traditional DW systems have static structure of their schemas and relationships between data, and therefore they are not able to support any dynamics in their source structure and contents, resulting in inconsistent results. A novel modeling technique is proposed to support such dynamics.
