With advantages such as cross - platform , language - independency , and practicability , corba ( common object request architecture ) , the mainstream of doc ( distributed object computing ) , has been widely used , making it the de facto industrial standard 分布对象计算( distributedobjectcomputing )的主流技术? corba ( commonobjectrequestarchitecture )因其跨平台性、与语言无关性及其实用性已成为事实上的工业标准,得到了广泛应用。
The goal of our research work are to create a new generation architecture for object - web services , to combine web technology seamlessly with distributed object computing technology , and finally to develop a new generation of distributed object computing architecture based on web 本文研究工作的目标在于建立新一代的对象web服务体系结构,以实现web技术与分布式对象计算技术的有机结合,发展出新一代的基于web的分布式对象计算体系结构。
As a mainstream technology in the distributed object computing , corba has many advantages in distributed applications , such as , independence of platform , independence of implementation language . thus it can conveniently be used to integrate the existing software in different network environments . through corba , distributed objects can interact each other in a very simple way , which they do n ' t need to deal with the tedious lower level network communication details 研究和应用实践表明,作为分布对象计算主流技术的corba技术能够在异构环境下方便地集成现有软件、屏蔽复杂的网络通信、提供统一的对象交互平台;而协同技术具有协调网络中多种组件、使多种组件相互配合、协作完成复杂任务的优点。
Finally , we design the next generation comparison - purchasing system , shorten as ngcps . this system combines web technology with distributed object computing technology , and extends the three - tier b / s architecture . dcom is used at the server side and the soap is adopted for conimunication across internet and ~ resentation of web service 本文基于上述研究设计了下一代比较购物系统( ngcps ) ,系统集成了web技术与分布式对象计算技术,并对三层b s体系结构进行了扩展,即服务器端环境采用dcom模型,跨internet的访问和web服务的展示采用soap协议。
The thesis provide a blue print to the distributed telemedicine system ( dts ) which is based on corba . with the anylysis of dts ' s system requirement under corba foundation , the object - oriented method and the characteristic of distributed object computing ( doc ) , we design a system architecture according with dts and discuss some key points in applying distributed computing technolegy ( dct ) to build dts 在分析了基于corba的分布式远程医疗系统需求的基础上,利用面向对象的方法,结合分布式对象计算的特点,设计了符合分布式远程医疗系统的特点的系统层次架构,讨论了应用分布式计算技术构建远程医疗原型系统的过程中的一些关键技术,并予以实现。
Uml and corba technology act as an important role in the area of ooa and ood and distributed object computing . the integration of them will help the integration of different modeling technology , different implement technology and different phases . this integration is very useful to design and implement of distributed object system Uml和corba技术分别在面向对象分析和设计以及分布对象计算领域起着重要作用,它们的结合有助于将不同的开发阶段、不同的建模技术和不同的实现技术有机、无缝地集成,对于设计和实现高质量的分布对象系统有着重要的意义。
In all , ngcps , which is established based ii on object - web service architecture , successfully demonstrates that distributed object computing model has been seamlessly transfered to the internet environment , it not only makes it easy to realize the interoperation among different models , but also extremely extends the function of web applications 最后探讨了ngcps系统的扩展问题,并实现了与internet上现有服务的集成。总之,基于对象web服务体系结构建立的ngcps系统成功地演示了将分布式对象计算模型无缝地迁移到internet环境,不仅轻而易举地实现了对象模型之间的互操作,还极大地扩展了web应用的功能。
