基于DCOM和MIDAS分布式联网订房系统的研究
|
摘要
在系统需求明确之后,开始对系统需要用到架构、数据库以及关键技术进行选型、预演。对多层分布式体系结构展开了深入研究和对数据库管理平台进行系统分析的基础之上,对系统的需求原型进行分解,把订房系统按业务单元进行模块划分,并对各业务模块进行详细设计,提出了一套基于COM/DCOM和MIDAS技术的分布式联网订房系统的实现方案,最后对开发过程中遇到的技术要点、难点进行总结分析,并指明系统的不足之处,提出改进设想。
The number of Internet applications is increasing rapidly,and the traditional reservation business also develops toward the direction of computerization and networking. After the system requirements are confirmed,lectotypes and rehearsal will be done for the required architecture,databases and key technologies. The research on the multi-tier distributed architecture is carried out and the database management platform is analyzed systematically. This paper puts forward a scheme of the COM/DCOM and MIDAS technology based distributed networked booking system,and decomposes the requirement prototype of the system. The reservation system is divided into several modules according to the business unit,and the detailed design of each business module.Technical points at the end of the encounter in the development process,difficulty analysis,lessons learned,and points out the shortcomings of the system,puts forward the improvement plan.
