Design And Implement Of Lottery System Based On Android And IOS

With the rapid growth of mobile users and the rapid popularization of intelligent mobilephone, intelligent terminal and application is becoming more and more importantin people’slife. As the same time, it has a large number of users buy lottery.But the traditional personentity betting payment cash purchase paper lottery approach greatly reduces the mobile userto buy lottery enthusiasm, also need to save paper lottery prize also greatly influencedpeople’s willingness to buy.In this artile, we throught the research of domestic and international systemthat mainlyused mobile phone or intelligent terminal to purchase lottery ticket, compare the process andtechnical architecture. Then uses Xcode development platform and Eclipse open sourcedevelopment platform to design and development the mobile lottery system.This systemwhich based on Android and iOS exchange data by TCP message, use of middleware todistribution transation message, and use the Sybase database system to store and manage data.This system mainly includes Android and iOS client, data transfer model, electronicpayment, electronic lottery, lottery prize drawing background application service. It will bedivided into external interface layer, business logic layer and database layer in the logic level.Theyare independent of each other, communicate by interface.Ituse message queuetransaction to distribution and processe data to improve application threads use rate.Ituse theOPENSSL protocol, to achieve key and certificate management, encryption and signaturedata to prevent data from being tampered with and steal.The system after experiments and tests,it prove thateach part can successfully runcorrectly, and can support millions of users to buy lottery ticket. What’s more, this systemreach the design of the functional and performance requirements, also for the mobile phoneterminal diversification of the bulk of the adaptation test, it proved that it have very stronge’sadaptation ability.
