摘要

View Generator (VG)是一个系统,它为远程web可访问数据库上的视图的定义、具体化、存储、维护和重用提供了必要的组件。通过该系统,客户可以识别感兴趣的Web数据库,访问其元数据并创建可由其他客户共享的个性化视图。与直接向数据源发出复杂查询相比,创建个性化视图提供了一种更有效的数据处理方式,特别是在本地资源稀缺、带宽有限和通信成本高的轻量级和无线客户机的情况下。使用移动Java代理实现的VG的多层体系结构允许自动代码部署以及视图的动态重新定位。

View Generator (VG): a mobile agent based system for the creation and maintenance of Web views
The View Generator (VG) is a system that provides the necessary components for the definition, materialization, storage, maintenance and re-use of views over remote Web-accessible databases. Through the system, clients identify Web databases of interest, access their metadata and create personalized views that can be shared by other clients. Creating personalized views provides a more efficient way of data processing than directly issuing complex queries to the data sources especially in the case of lightweight and wireless clients that suffer from scarce local resources, limited bandwidth and high communication costs. VG's multi-tier architecture implemented using mobile Java agents allows automatic code deployment as well as dynamic relocation of views.
