摘要：In this paper, we adopt e-commerce technology to realize a house lease management system. Our proposed management system has three important advantages as follows. First, users can release or update their house lease information any time or place by using an Android smart phone to access the wireless fidelity （Wi-Fi） and 3rd-Generation （3G） mobile network. Second, the system provides functions to inquire and browse house lease social networks for those customers who want to lease houses. Finally, taking advantage of global position system （GPS） information, the presented system can plan the best route for brokers and enable customers to track the brokers. The real estate brokers can edit the path to meet the customer＇s requirements.
