Yunnan-guizhou Chuanfu Li Lottery Hotline To Jointly Sell The System Design And Center Management System Development

The national computer welfare lottery ticket system like a raging fire development has started since 2000, national 31 provinces, the municipality, the autonomous region already have all cleared the entire province networking computer welfare lottery ticket system, moreover passes through four, five year rapid development, the computer welfare lottery ticket system has experienced several different development phases, now already develops to the entire hot line stage, the sales scale already has sold by oneself from an initial alone province, develops to a many provinces union sale even nation union sale big collective scale.The this article main detailed introduction independently develops and the implementation by the author, three provinces successes carries on the union sale south the Yunnan and Kweichow western Sichuan a computer welfare lottery ticket hot line system successful case.We chose based on the COM + technology multilayered distributional system structure had taken this development the system structure, used Sybase Adaptive Server Enterprise 12. 5 to take the backstage database, used the ADO data accessing using the server to the data server between the connection way, used the DCOM data module using the server to the client side between to realize the multilayered distributional system, but coded the realization then used PowerBuilder and Linux G++ carries on the multilayered database application development as the development kit (MIDAS).In this system, sells the stand registration and so on the basic information as well as the sale exchanges the prize and so on the detailed primary information all to deposit in IBM H80 in the series RS/6000 enterprise server center database server. But among service machine and communication server then use the COM+ technology to provide the manykinds of middlewares service, these service core functions are the data inquiry, the creation, the revision and so on.Uses the highly effective parallel processing ability and the MIDAS technology, the mass sales stand may to the communication server transmission request, the communication server carry on verifies and retransmits requests to the among service machine, through among service machine connection to center database server data pool execution operation, more convenient batch data processing. The data processor is the user graphical interface procedure, slights the law the new sales cycle starts, as well as the data compiles, opens the prize, sends the color and so on all work all to complete in this procedure. This system innovation place lay in before take the province as the sales unit' s computer welfare lottery ticket system, expanded to many provinces union sale take the region as unit's computer welfare lottery ticket system.
