摘要
现有的移动数据库体系大都是在传统的基于固定网络的分布式数据库技术的基础上进行改进,但是这些改进并不能真正满足需求,尤其是当移动用户规模变的十分巨大的时候,这些体系就会明显的暴露其缺陷。对Agent和Multi-Agent的研究近几年来已成为分布式人工智能研究的一个热点。Agent是具有拟人智能特性的、驻留与活动于客观世界中的实体。Agent技术的自主性、主动性、反应性、移动性和社会性等优良特性,使它非常适合移动计算环境,理所当然成为实现移动数据库体系的首选。该文系统、深入地研究了基于Agent的移动数据库体系的模型系统,并实现了其在移动业务处理系统中的一般应用。
The characteristics of Mobile Computing make it difficult to apply the traditional technology of distributed database in Mobile Database architecture directly.However,all kinds of current technologies of Mobile Database are still improved on traditional technology of distributed computing and distributed database in order to be suit for the needs of mobile computing environment.But these improvements can't meet the needs of mobile clients indeed,especially when the scale of mobile clients become very large.The agility of mobile computing needs a certainly kind of agile technology to fit it.The study on Agent and Multi-Agent has became a hotspot in the field of Distributed Artificial Intelligence in the recent years.Agent is the anthropopathic entity staying and moving in the real world.Agent technology has many in-telligent properties such as autonomy ,activity,reactivity,mobility and sociality,which makes it adapt to mobile computing environment very well and go without saying to be the best choice to realize Mobile Database System.This article ana-lyzes the current technology of Mobile Database and Agent technology carefully.In the second half of this article,it re-searches on the key technology and model of Agent-based Mobile Database and its applications in Mobile-Business.
