Item location stationSelection StructureIn order to implement the item look-up station at every networked Wal-Mart outlet, information related to the items as well as the associated stores will have to be saved in the local database in the form of two separate arrays of two types of objects. An ‘Item’ object would contain information such as item name, item code, category of item, quantity available in store. An array called ‘Items’ would represent all items in the local store.A second array called ‘Stores’ would be stored at each station containing the information of all the networked stores where the items are likely to be found and are to be searched in.

Every ‘Store’ object would comprise of the store id, name, its location, phone number, distance from the current station. The ‘Stores’ array at each station would already be sorted according to the lowest distance.In order to avoid invalid entry by a customer, the station would present the customer with a fixed list of categories to choose the item from. When the customer selects an item from the list, a local search is conducted within the array ‘Items’ of the local database. In case of a match and if the available quantity is greater than 0, the information is presented to the customer.

In case no match is found, the item is searched in the ‘Items’ array of the nearest remote store location i.e. on the server of the first store in the ‘Stores’ array. The search continues for all the stores in the array. Information is presented only if the item exists in a particular store.A while loop is used to traverse through all records of items and stores, while the matching conditions are checked through the if-statements.PseudocodeStep 1: Display MenuStep 2: Get Item Name from CustomerStep 3: Match Item name with Items in Local StoreStep 4: In case Item available Step 5: Print Message “Available”Step 6: Print Quantity of Item AvailableStep 7: In case Item unavailable at Local Store Step 8: Match Item Name with Items in Nearest Store Step 9: In case Item Available Step 10: Print Message “Available” Step 11: Print Name, Address and Phone of the Store Step 12: Repeat Step 8 to 11 till all Stores are searchedStep 13: Ask Customer to make another searchStep 14: In case Cusomter selects to search again Step 15: Goto Step 1Main Declare maxStores as Integer Declare maxItems as Integer Declare count as Integer Declare found as IntegerSet maxStores equal to 5Set maxItems equal to 20 Declare Private Items[maxItems] as Item Declare Private Stores[maxStores] as Store Items = IntializeArrayOfItemsFromFile() Stores = InitializeArrayOfStoresFromFile() Call Method DisplayMenu() Input ItemName Initialize count to 0 Initialize StoresCount to 0 Set found to 0 Declare choice as Character Set choice to ‘y’ While choice is not equal to ‘N’ Set choice to ‘n’While count is Less than maxItems If Items[count].
