Abstract


With database technology and network technology development , distributed database system has matured not only in theory but also in grid computing , Internet applications, data warehouses , etc. are increasingly extensive application . As distributed geographically distributed databases have sex , how to effectively solve the problem of data consistency is to ensure that distributed database systems play a key role . Data replication is commonly used in distributed database application , a data copy technology , and its role is to provide a copy of the data on multiple hosts , for the release of information in distributed environments to provide fast and effective means. To ensure data synchronization , consistency also can improve the access performance data query , enabling remote users to copy data to complete local references distributed operation , reducing network and the central database server load. This paper analyzes the theory of distributed database systems , discussed in detail the basic concepts of distributed database systems , system architecture, model structure and transaction management ; pairs of data replication technology in a traditional relational database implementations , data conflicts during replication Workaround research. Combined Shanxi Electric Power Corporation Web site management system (Shanxi electric power corporation ContentManagement System) the practical application of the data replication model in-depth research, research in the data replication solution to the conflict ; proposes a modification timestamps based on data recorded data replication method , the use of the method is designed to achieve read-only data replication solutions application model . And applied Shanxi Electric Power Company website management system , to solve the practical application data subscriptions replication needs, achieve a better effect .
