Data Migration Technology And Its Application

In the information construction process, with the development of technology, the existing information systems have been replaced by new system function more powerful, is bound to face a data migration problem. And the data transfer is successful or not is an important prerequisite for the successful launch of new system, the new system also ensures its effectiveness and stability.Successful data migration or not is an important prerequisite for the successful launch of new system, the new system also ensures its effectiveness and stability. If the data transfer failure, the new system will not enable. If the poor quality of data migration, can not shield all the garbage data, the new system will affect stability. On the contrary, the success of data migration can effectively guarantee the smooth operation of the new system, to preserve the historical data, which is very important to the telecommunications industry.This paper introduces the basic concepts of data migration technology, and system resource management system of BOSS system data migration as an example, introduces the data migration of the preparatory work, design and the implementation work, Includes determining a data object migration, data migration framework, database modeling and implementation of case etc. At the same time to data migration factors to effect data migration in the application process, such as source and target system control model, system data quality, gives the corresponding solutions, to ensure that the data from the source system to a target system transition smooth and conversion, guarantee accurate and continuous availability.
