摘要
在基于对等网的异构数据集成系统中,部署在各个异构数据对等体上的数据库系统具有分布性、独立性和异构性。对等体间的数据信息需要双向交互和即时通信,实现信息共享。鉴于对等网技术的动态发现和交互通信的优点,本文提出了将包装器和JXTA通信适配器相结合的即时通信系统,分为数据提供对等体、中继转发和数据请求对等体三部分,从而实现异构数据对等体间数据库信息的即时通信。
In the heterogeneity data integrative system based on P2P,the database system which is deployed on each heterogeneous data peers has the distributed,independent and heterogeneous character.In order to share data,the bidirectional alternating and instant messaging between the peers is needed.In view of the P2P technology's merit of dynamic discovery and interactive messaging,an instant messaging system is proposed which combines the package and the JXTA correspondence adapter.The system includes three parts:provider-peer,transfer and request-peer,to realize instant messaging between the heterogeneity data peers.
