| Distributed database system may be regarded as a series of union of centralized database system. Data distribute different node in computer network.The data distributes in the computer network different node,but distributed on the physical structure. It develops on the basis of centralized type ripe technology of database system, but does not realize the centralized type database separately briefly. The distributed database system is regarded as the important field of information processing discipline and infrastructure of the information system, in developing rapidly.This text has made a brief instruction to the distributed database system since the distributed system is defined, evolution and characteristic. The design and application of the distributed database system realizes carrying on analysis and research, discuss that goes on general method and route that the system is designed. Until data resume and erupt simultaneously, control foundation analyzed to go on to basin information management, the distributed database system of the discussion employs some key technology involved, including the data resume, erupt controlling and safe respect implementation tactics and method simultaneously. Have carried on analysis and research to the application in the information management of basin of distributed database especially. Provide data thinking and method of distributing the tactics of information management of basin. The distribution on data physics of comprehensive analysis and logical distribution type, combine the actual need of the information management of basin, confirm the distributed database employs the necessary systematic system structure. Carry on research to the mechanism of access to data. Provide the interface of daily access to data, discuss to treatment and optimization that inquire. Finally, carried on some analysis and research and explored to the database application and development based on internet environment in the information management of basin. |
