In the process of normal customers'lottery behavior, they focus mainly on the convenience of operation, the security of capital and the experience of using the software, so these pointed are considered in designing the system. When discussing the demands of the 3rd party partners, the process of renting the lottery service and lottery through the Internet is considered. Interfaces of the lottery platform and operation process are analyzed and designed as well as the safety of the interface and the data model.(2) Analyze the architecture according to the demands, including the architecture of software as well as the topology of the system. The whole system is divided to 3 sections:the user interaction module, lottery operating system and lottery ticketing system. And then the processes of interaction between different systems are discussed in the paper as well as the interface, which is offered to the 3rd party partners.
