Inventory data in the legacy UDB environment does not meet all the analytical requirements of both the food and general merchandise businesses. By ensuring inventory data meets these analytical needs we will be enabling more timely, accurate and actionable reporting to be delivered back to the business via our parallel partner projects: 2012 MBI reporting release, Presentation & Space Reporting and Strategic Planning Funnel reporting. By implementing a more retail industry specific model and leveraging our learning's while building FMA\Unsalable marts, Target will be better positioned to anticipate future market trends and leverage its own inventory data more effectively. Inventory was initially implemented in the legacy UDB environment as a part of the Food Merchant Analytics (FMA) project but had a decidedly “food” slant to it. During the course of us

Re-plat forming analysis the project team identified a number of Logical and Physical recommendations to improve the architecture and usability of this data for General Merchandise.
