According to recent statistics, the number of one-person households is increasing continuously in korea, and one-person households is the most representative living arrangement. Consequently, home appliances and services for one-person households are actively launched in recent. A web-based order management system is proposed in this paper, which is useful for managing orders for one-person households. In recent, applications in smart-devices and web systems are actively used for managing orders and deliveries efficiently. However, in conventional applications, orders for one-person households are considered being of little importance. This is because it is uneconomic due to the high cost for delivery. In the proposed system in this paper, a delivery cost is diminished by managing orders for one-person households in a database and comparing their addresses for each other. By the mechanism, the success rate of orders by one-person households can be increased, but the processing time for the orders can be decreased. Therefore it can manage orders for one-person households efficiently.
