【摘要】 文中论述了如下概念:基于P2P网络上保证在网络出现故障时,顺利读取数据。基于数据安全,提出数据冗余的概念,包括在本地设置多个备份数据库服务器,在主服务器故障的时候,可以使用备份数据。还有在不同的地方,设置服务器。提出分布式系统后,就出现分布式数据库,这样只能保证在服务器端的数据库的数据完整性。但是,对于客户机是没有保证的,一旦与主机的连接出现问题的时,分布式数据库就发挥不出优势。现在,P2P的技术加上的分布式数据库的技术,就可以解决分布式数据库的网络与数据库的问题。更多还原

【Abstract】 This paper presents the concepts as follows: the smooth read of data could be ensured while the failure appears on the P2P-based network; based on data security,the data redundancy concept is proposed,including the local installations of multiple backup database servers,thus while the main server is failed,the backup data could be used. The servers are also set up in different places. When the distributed system is proposed,the distributed database appears,thus only the data integrity in the database server side could be guaranteed. However,there is no such guarantee for the client that once there is some problem in the connection with the host,the distributed database could not give full play to its own advantages. Now,by integrating P2P technology with the distributed database technology,the problems of distributed database network and database could be successfully solved.更多还原
