| Abstract: | The data increment renovation is the primary question in the field of using data bank.Based on the design for getting increment data,the research on the redundant question of increment data is carried out and we put forward the preprocessing method and design the corresponding algorithm,realizing the condense of increment data,improving the quality of increment data and the processing efficiency of ELT process.We give the specific realization of increment ELT process. |
