| Abstract: | The data warehouse can not be formed by a simple accumulation of data in traditional database.And it is a complicated system engineering that gathers the data and integrates them,provides the power of access,analysis and share for decision maker,so develop the real effect of the data warehouse.This paper aims at illustrating the process of the ETL in retail trade data warehouse,and combining the actual application brings forward the problems which should be considered in the process of the ETL in retail trade data warehouse as well as the relevant resolvent. |
| Keywords: | retail trade data warehouse ETL data extract data transform data cleaning data loading |
