Use Case Description: ABC Supply Company needs to keep track of their office and computer inventory in order to reduce costs, manage reorder points, and better track item locations within their facilities. They need to track which buildings contain what products and be able to contact the manager of each building to verify inventory and reorder products, when necessary. The New Technology Center (NTC) is a building managed by Ingrid B. Johnson, while the Candice Simms Foundation (CSF) Building is managed by Mary B. Carter. Both managers have access to the central building phone number Buding LID 555 Currently, one of the administrative assistants keeps track of office furniture, computers, servers, printers, scanners, printer toner, etc. using a simple spreadsheet. It looks something like this with just a sample of five of the items tracked: Item Item Room Vendor Vendor Item Quantity on Item Quantity on Number Name Number(s) Name Hand Order 231134-678 HP Deskjet New Technology 325, 100 Sam's Supply 895Cse Center Store 342245-225 HP Toner New Technology 325 Sam's Supply Center Store 254668-449 DT Scanner Candice Simms 123 John's Foundation Warehouse Building 254678-449 DT Hard Candice Simms 100 Electronic Drive Foundation Depot, Inc Building 3478 496 DT 400 Cable New Technology Building Electronic Depot, Inc Normalization to the third normal form (3NF) involves: 1. Being in 2NF. 2. Containing no transitive dependencies. (2NF) Item (Item Number, Item_Name,) Location (Building, Room_Number) Vendor (VendorID, Vendor_Name) Inventory (Item_Number, Room_Number, Building, Item Quantity on Hand, Item Quantity on Order)
