Abstract :
The design of extract transform loading (ETL) aggregation policy for data warehouse in LTS is introduced in the paper. Firstly, we analyze the characters of data storage in LTS, and according to the subject and logic model analyzed to LTS, estimate the data scale and classify the refresh frequency, then design the ETL aggregation policy, including aggregation tables and the process of aggregation transformation. The paper proposes new and be executed rules for selecting aggregation dimension and presents the process of aggregation calculation and transformation.
