The client side and the service side, which people in the Intemet sharing behavior on the upgrade to a more general level, people involved in a more proactive approach to the network. 2.4 Pervasive Computing Pervasive Computing (ubiquitouscomputingorpervasivecompu-ring) emphasizes the close links with the computing environment, so that computer and network more effectively integrated into people's lives, so that people at any time, any place can be convenient and efficient access to network computing services provided. Pervasive computing research mainly includes the natural human-computer interaction and network computing. Universal computing model subversion of the lJ3 the development of network computing C / S structure,Links of London Charms, became the mainstream of computing technology, system integration is the key to good sex. However, with today's distributed enterprise computing, scalability, and heterogeneity and other requirements make the C / S structure encountered great challenges. Technology trends from the point of view, we realize that B / S computing model will eventually replace the C / S computing model. But at the same time, we clearly see that, as has been the formation of the network status in the next period of time, the network computing model is likely to be B / S, C / S hybrid computing model exist. 3.1ActiveX model of Microsoft's ActiveX platform is the basis of the distributed computing environment for users to develop Intemet / Intranet application provides a new environment. ActiveX technology, including: ActiveServer (server), Activedesktop (desktop) and Active technology. This technology has the cross-platform, and programming language independent, for documents and components and so on. 3.2CORBA model of CORBA (CommonObjectRequestBrokerArchitecture) Common Object Request Broker Architecture is the application made by the OMG software architecture and object specification, the core is a standard language, interface and protocol, heterogeneous and distributed applications to support inter- interoperability and platform-independent programming language and object reuse. 3.3Java Java computing model launched in 1995, with its excellent portability, with the various platforms on the network even as the overall capacity. JAVA is an application development platform, in accordance with the high-performance, portable, explain the principles of object-oriented programming language and runtime environment. JAVA is the essence of calculating the distribution to take advantage of the various objects in the network together to complete the corresponding task. [5] |
