基于.NET与WCF的民航订座系统研究

Research of civil aviation reservation system based on .NET and WCF

为解决民航信息系统集中式紧耦合体系结构引起的业务功能扩展不灵活、系统优化及维护困难等问题,针对核心系统之一的订座系统,设计了基于.NET平台的多层、分布式系统结构,并结合WCF(Windows communication founda-tion)技术对业务组件和数据访问进行封装,使服务具有原子性,更易于移植和功能扩展。为避免网络通信费用,系统在局域网中模拟实现,实验结果表明,采用.NET平台和WCF技术构建民航订座系统的方案是可行的,可以推广到民航其他信息系统。

To solve the inflexibility of business function extension and the difficulties of system optimization and maintenance due to centralized and tightly coupled architecture in civil aviation information system, a multbtier distributed system architec- ture of reservation system which is one of the core systems in civil aviation is designed based on . NET Framework, and the servers which are atomical, portable and extended easily is accomplished with WCF, the business components and data access are packaged by WCF. Implementation of the system on a local network without cost of network communications suggest it is feasible that civil aviation reservation system is reformed based on. NET Framework and WCF, and it can be extended to other civil aviation information systems.
