【摘要】 该文主要讨论在综合计费帐务系统后台用C++实现一个统一的数据库接口模块,以实现对数据库Oracle和Altibase统一的访问.统一数据库接口对外提供比较简单的数据结构定义和接口函数,内部封装了针对不同数据库的编程实现,减少了程序的复杂性,并且增强了程序的可移植性和可扩展性.更多还原

【Abstract】 Using C++ to developing and applying the unified database interface module in the background of Integration Bill Account System are discussed in this paper.It can use the unified codes to operate the different databases.The unified database interface can offer simple definitions of data structure and interface functions in the out side and encapsulate program implement to different databases insides.All that can reduce the complexities of programs on the one hand,enhance the transplants and expansibilities of programs on the other hand.更多还原
