Research And Implementation Of The Incremental Information Processing Method In Telecom Data Migration

As the extensive and long-term use of computer business systems in telecommunications industry, telecommunications companies already have a large number of customers and business data. Scientific management and rational development of these internal and external information resources has become a key of correct decision-making and competitiveness strengthening. In order to better analysis of existing data to decision-making, many carriers choose the operating analysis system.As a Subject-Oriented, Integrated, Non-Volatile, Time Variant data warehouse, Operating Analysis System help carriers make full use of valuable information resources generated by its business support system, realize intelligent information processing and handling for market operators, so as providing timely, accurate and scientific basis for decision-making to enable enterprises to adapt to the increasingly fierce market competition environment and raise the operator's core competitiveness.With the enterprise data warehouse data continues to increase, the structure of data warehouse keeps on escalating, moving historical data in the old data warehouse to the new data warehouse gives birth to data migration technologies. Telecom data migration involved in different stages of data warehousing, with a system of different modules, and how to migrate the data efficiently and quickly become an issue of great urgencyThe main work are listed as below:(1)Participated in the system analysis of some province's operating analysis system, and be responsible for the design and implementation of data migration subsystem.(2)Designed incremental information processing method as the core data migration method, applied this method to data migration and improved the structure of the data migration subsystem.(3)After designing and implementing the improved data migration subsystem, Applied the incremental information processing method to practical data migration and achieved good result. The research results of this paper has been applied to the data migration subsystem of some province's operating analysis system and achieved good results, and the application experience provides good lessons for other data warehouse module.
