摘要/Abstract

摘要： 定义了适用于P2P文件共享的数据基因模型,并给出了基于数据基因模型的P2P文件共享平台的体系结构。这一文件共享平台利用文件的数据基因组来组织和管理共享文件。由于同一文件的不同版本拥有不同的基因信息,它们可同时存在于系统中供用户使用,因此数据一致性问题得到简化。由于可利用文件数据基因组中对相关文件的记录进行查询处理,系统查询实现更高效。文中还给出了此文件共享平台的数据查询算法与更新策略。

Abstract:

A data genome structure of file used in P2P file sharing platform is presented at first.Then the architecture of a P2P data sharing platform based on data gene model is proposed. In this platform files are managed by using their genetic information.Different version of file can exist concurrently for they have different bur relevant data genomes.Therefore problem of data consistency is simplified.And using associating information in data genomes query can be processed efficiently.The query algorithm based on data gene and update strategy are given also.
