Design And Implementation Of Online Transaction System Based On Android

Now models of e-commerce transactions are changing to brand-driven,which is a consumer-oriented and sustainable development.In this model online transaction system is not only one sales platform,but also an important tool to promote and disseminate brand.The consumer-oriented brand-driven should also provide the users more convenient service,such as those interesting goods recommended and timely information notice.With the popularization of intelligent mobile devices and the wide use of modern internet technology,online transactions are translating from traditional webpage to applications of smart devices.In order to meet the needs of users to adapt to the trend,this subject is to use C# to build one client online transaction system based on Android,the most operation system for mobile smart devices,and develop a cross-platform,distributed and online transaction server-side system with a recommendation system,information notice and a commodity alarm system,to provide users with friendly human services.To use one basic platform composed of database,J2 EE application server,.Net Framework,basic business framework,etc.,and through the platform this system can communicate with the business logic layer and the external big data system COMSMOS.The basic business framework is a service-oriented architecture that integrates the recommended algorithm engine and rights management,and with the framework this paper is to design and implement the key functional modules: mobile client,order managerment,payment managerment,recommendation function and alarm management.This system not only allows users to complete the transactions through Android,but also generates the user's personal products recommendated according to the user's purchase records,habits and other characteristics of the information,and what's more,the system can provide the businessmen the future popular commodity prediction according to the current stage of merchandise sales.And the recommendation is based on one hybrid recommendation algorithm combined with the item-based collaborative filtering and user-based clustering algorithm,and this system runs on one big data system COSMOS.Alarm management will take effect on and send out replenishment emails or messages via SMS platform to sellers when amounts of merchandise inventories are lower than the alart values.Database managerment uses Master-Backup-Slave for read/write splitting to make sure the system owns a good perfermance on immediate response.Security managerment uses Bcrypt algorithm to encrypt passwords and uses the mix of symmetric encryption and asymmetric encryption for the translated transaction information.Finally,the online transaction system is tested from three aspects: function,performance and security.And the results show that the expected design goal is achieved.To design and implement one online transaction system based on Android,owning the merchandise recommendation and monitoring serverices for different customers and businessmen.It has a certain reference value for the related software investigation on e-commerce.
