    The document outlines a data flow diagram of a point-of-sale (POS) system at three levels. At level 0, it shows the main processes of a POS sale, purchase order, stores database, and invoice. Level 1 breaks these down into sub-processes like viewing products, adding to cart, authentication, and generating reports. Level 2 further expands the order process into steps like proceeding with payment, payment confirmation, and interaction with the bank.
