基于P2P的实化视图维护技术研究

基于P2P的视图维护是一个重要的研究方向。当前的视图维护方法主要以传统的C／S模型为基础，当更新频繁时将会导致数据仓库超载而崩溃。针对这种现状，构建了基于P2P的主动视图维护模型，模型充分发掘P2P技术的潜在优势，克服了传统视图维护方法中数据仓库和数据源负载失衡及可伸缩瓶颈等问题。描述了P2PAVM的节点拓扑结构；重点阐述了P2PAVM的动态节点管理与路由等关键技术。

Research on P2P-based View Maintenance

View maintenance is an important research area in Peer-to-Peer technology.Currently,most view maintenance methods are based on the traditional C/S model,which will lead to the overload and crash at the data warehouse.To address the problems,the model of P2P-based active view maintenance (P2PAVM)is established,which can not only exploit the potential merits of P2P, but also overcome the problems of traditional view maintenance models (e.g., overload unbalance between data warehouse and data source,lacking of scalability).The topology of the peers in the P2PAVM is presented.The key issues of implementation are described,including dynamical management and routing of peers.
