电子商务能够提高企业的效率、增强企业的竞争力,因此,电子商务作为一种新型商务模式正在全球范围内迅猛地发展。但是在其发展过程中,人们渐渐感觉到传统的电子商务实现技术已不能适应Internet上信息膨胀、传输负荷过重的状况。人们急需一种新的技术来建立快捷、高效、智能化的电子商务系统。 近几年来,agent的研究广泛兴起。这一技术快速发展的一个主要原因就是其执行任务的方式具有明显的优点,以及使用agent可以帮助用户从纷繁的信息海洋中解放出来。移动agent是agent技术与分布式技术相结合的产物。它能够按用户的愿望自动地在网络上迁移,能够根据环境的变化自主地采取对策,能够在完成任务后再将结果返回。将移动agent技术引入Internet应用已成为当前国内外学者和企业研究的热门课题。基于移动agent技术的电子商务系统能够为消费者和商家提供智能化和自动化的代理服务;大大降低网上商务活动的通信代价;满足了电子商务中的移动式计算、软件的自动升级安装、网上信息发布查询和收集等需求。它弥补了传统电子商务模式的缺陷,既适应了电子商务发展的需要,又可以充分发挥移动agent的技术优势。 论文首先分析了传统电子商务存在的问题,提出了基于移动agent的电子商务系统的设计思想;接着系统地介绍了agent和移动agent技术;然后深入研究IBM Aglet平台的体系结构、对象模型、消息机制和常用软件包;提出基于移动agent的分布电子商务系统设计框架,确定了基于移动agent的电子商务设计目标、系统部署、系统结构及其具体流程,并采用面向对象的方法对系统进行设计,提出数据库设计和系统安全方案。最后,为验证研究工作的科学性和实用性,开发实现了原型系统——“MP Bargain”手机购物网。
E-Commerce can improve the efficiency of enterprises and make it more competitive. Consequently, E-Commerce is developing globally in a swift and violent manner as a new type of commercial mode. However, in the course of its development, it is becoming clear that traditional E-Commerce technology hasn"t met the state of the inflatable information and the overweight transmit load on Internet. People need a sort of new technology badly to set up fast, high-efficient, intelligent E-Commerce system.In recent years, the research of agent has risen extensively. Agent technology is fast developing due to its advantageous method of executing tasks. Further, Agent can help to liberate users from a vast and complex ocean of information. Mobile agent (MA) is the combine result of agent technology and distributed technology. Firstly, MA can move according to the hope of user; secondly, MA can take action independently according to the change of environment; and finally, MA can return the result after finishing the task. Therefore, it has become hot research subject among the domestic and overseas scholars, as well as in the enterprise that applying MA technology on Internet. E-Commerce based on MA can offer intelligent and automated agent service for both consumers and enterprise; it can reduce greatly the communication cost of the online commercial activity; it can also meet lots of demands, such as mobile computing in E-Commerce, the automatic installation of software upgrades, and the issuance and collection of the online information. Thus, MA fills the gap left by traditional E-Commerce mode. It not only meets the need of E-Commerce development, but also gives full play to the technological advantage of MA.This paper analyses firstly the existing problem in traditional E-Commerce, puts forward the design thought of E-Commerce based on MA. Secondly introduces systematically the technology of agent and MA. Thirdly, lucubrates to the system structure, object model, message mechanism and the commonsoftware package of IBM Aglet platform. Then brings forward the design framework of E-Commerce based on MA, confirms the design aims, configuration, architecture, and concrete process of the E-Commerce based on MA, designs the system adopting Object Oriented Analysis (OOA), and proposes the design scheme of the database and the security. Finally, develops and realizes the Mobile Phone shopping net-"MP Bargain" to verify the science and practicability of research work.
