Design And Implementation Of Account Management System In Video Lottery Game

Information technology has been applied to the lottery system for many years. At present, the importance is explored to video lottery system, no-paper lottery system and credited lottery system. Nowadays, with more and more game developers, the operators could offer many different games to the player. This will result in operators spend much time to statistics player information and the popularity of games. Therefore, there is an exigent need to design a mature, reliable account management in video lottery games. The scalable account management system is based on Spring framework and Flex. It can be divided into four modules, including player account management, player token management, employee token management and system management. The thesis focuses on the client, the server and the integration layer. In order to enhance the interactivity of interface, the client side primarily uses Flex technique. Two different kinds of clients are designed to ensure data security and RemoteObject and WebService are employed to interact with the server. The server is divided into service API layer, business logic layer and data access layer. The implementation of server mainly uses Spring framework to organize the business objects. One enhancement is to add two phase commitment features in the system to ensure the data consistency between account management system and external systems. The server uses the reverse proxy to improve data throughput. The integration layer is based on Spring framework and combined with Apache CXF, BlazeDS to interact with other system. The main works are as following:1. The requirement of the account management system is analyzed.2. The service API layer and business logic layer of the server are designed and implemented. And two phase commitment features is designed and implemented.3. The interaction between the integration layer and the account management system is designed and implemented.4. The design and implementation of the client are involved.5. The interactions between the integration layer and other systems are involved.The system has been tested in CLS and the results show it is perfect. It has been proved that the technique and solution are effective in practical application. The work of this thesis obtains the good result with a doughty practicability and application value.
