- Dollar General Corporation operates deep-discount stores offering housewares, cleaning supplies, clothing, health and beauty aids, and packaged food, with most items selling for $1. Its business model calls for keeping costs as low as possible. The company has no automated method for keeping track of inventory at each store. Managers know approximately how many cases of a particular product the store is supposed to receive when a delivery truck arrives, but the stores lack technology for scanning the cases or verifying the item count inside the cases. Merchandise losses from theft or other mishaps have been rising and now represent over 3 percent of total sales.

- Scenario A combined cycle gas turbine power station requires a webbased system to manage the storage and installation of spare parts and the acquisition of new parts from the Central Storage Warehouse (the CSW). The powerstation maintains an inventory of all the parts it owns comprising: part name, description and specification. There are many copies of some parts – each part has a unique ID, known as an asset tag number. The asset tag number is used when there is damage to particular parts. The power station also keeps a catalogue of all the possible spare parts types used.Only registered maintenance engineers and team leaders are allowed to install and repair parts on the plant. Maintenance engineers and team leaders can use the parts catalogue tosearch for part types and can also search the parts inventory. Maintenance engineers work in teams, currently: electrical, mechanical and environmental. Each team has its own team lead. However, the system needs to be flexible enough to…Assume you're setting up a new room reservation system for your institution that keeps track of which courses are assigned to which rooms. Assume that each building's rooms are "owned" by one college or department, and that only one person in that college or department has the authority to allocate them. Which conversion approach would you employ?the requirements for TAL Distributors have changed. A number and a name now identify each storehouse. Units of each item may be stored in multiple storehouses, and it is important to know precisely how many items are stored in each storehouse. In addition, TAL Distributors now want to manage information about the suppliers from which it purchases items. For each item, TAL Distributors needs to know the number and name of each supplier as well as the expected lead time for delivering each item. (Lead time is the amount of time a supplier is expected to take to deliver the item after TAL Distributors has ordered it.) Each item can have many suppliers, and each supplier can supply many items. Using this information, convert the following unnormalized relation to fourth normal form:
