Has realized from the merchandise control, the classification of goods and the inquiry, realizes to the shopping cart, user order form processing, arrives at the chatroom again, the manager system. Basically has realized the electronic merce function flow, can realize the user and the business online carries on the modity exchange. This system contact surface simple directviewing, simplify operation and use, interactive is strong, pletely based on the Inter work.
