基于DCOM的分布式收费系统设计与实现

Design and implementation of distributed charging system based on DCOM

收费业务是一种常见的业务,而且一般具有灵活性和复杂性的特点。当其与分布式技术结合起来之后,更需要考虑空间离散化、时间并行化和数据共享等方面的问题。结合一个实际的供暖收费系统工程,详细地描述了分布式收费系统的数据模型,介绍了基于DCOM的多层系统结构的设计及实现,并且进一步给出了处理多用户并发访问的解决方案。

Charging system is a kind of familiar operation which is adaptable and complex. When distribution technology is used in it, aspects as dispersedness in space, parallelizability in time and data sharing are considered. Combined with a real charging system for heating system, the data model of a distributed charging system is given. The design and implementation of multi-layer system are introduced based on DCOM, and the solution of multi-user access is proposed.
