【摘要】 无线服务后台软件即C++ 客户端应用程序,采用CORBA技术和JaguarCTS三层体系结构开发。三层结构体系中,客户端很小,简单通用,大部分的应用驻留在网络中间服务器上,中间服务器再访问数据库,完成客户端的请求。通过中间件技术平衡网络负载,解决跨操作系统,跨协议等兼容性问题,实现分布式软件集成。在JaguarCTS三层结构基础之上,进一步延伸客户端,灵活构造系统结构。并利用C++ 面向对象特性打通数据传输通路,建立CORBA Jaguar C++ 客户应用,实现了无线终端访问网络数据库。更多还原

【Abstract】 The wireless service software is the C++ client application developed with CORBA and JaguarCTS technology. In three-layer structure, the client terminal is simple and universal, and most of the logic applications are reside on middle server in network. The middle server accesses the database, and completes the clients requests. The load in the network was balanced, the compatible problem among different operation systems and protocols was resolved, and integration of distributed software was realized with middle-ware technology. On the base of three-layer structure of JaguarCTS, the client terminal can be extended, establish agility system structure. Data channel was gotten through, CORBA JaguarCTS client application was established using C++ Object-Oriented technology, and the wireless terminal directly querying network database was realized.更多还原
