Why supermarkets use database?

Answer 1

Most systems have the following categories: - Barcode (which can be used as the key) - Manufacturer - Price - Cost - Quantity - Expiry date (sometimes, depending on the retailer and the product) - Some retailers maintain a separate product number, which frankly doesn't make sense. Since the Barcode is always a unique number.

Answer 2

Like any other business, there are many things a supermarket needs to keep track of. For example, their employees and what shifts they are scheduled to work. The database can also be used to track inventory and suppliers.

Answer 3

Till systems use a differing system to a standard network. Many have a master and slave till associated to the master. The master will download to its main system barcodes, descriptors and price point plus the operating system for its features like card reader, scanner, printer, draw mechanism. This allows a degree of "stand alone capability". Sa transactions are completed (items scanned, system is subtotaled for the customer to know purchase value it then allows inputs of payment methods such as coupons/vouchers - again subtitled for new values. The system then will be promoted either to pay cash, credit card a mixture of both. The Epos system then communicates with the "back office" which holds inventory, cash transactions, sales data including how payment is made and also, if used checked credit/debit cards against the hotcard file (this is stolen/fraudulent card data). On completion of the sale the receipt is produced and the sales data sent to back office to adjust inventory, calculate department sales and add in to the running sales totals (including recording debit - credit card sales, coupons used - cash used)

In the event of an "Off Line" event where the back office main system stops communication with the front of house tills some systems can run using the master slave system to record fr a period of time. when communication is recovered the back office will call the data back and "recover" its last know position.

The actual register/till holds very little stock information but focuses on the cash/debit card flow as stock can be inventoried later to correct discrepancies where its a security issue if financials are not stored.
