Claim 2:
3. The data processing method according to claim 1, wherein the dimension table comprises a plurality of pieces of dimension data and a change in each piece of dimension data, and the event table comprises a plurality of pieces of event data and a change in each piece of event data,
wherein the filtering through the full data to obtain the incremental data, sorting the incremental data and storing the sorted data in the dimension table and the event table of the data warehouse detail layer comprises:
filtering through the full data stored in a corresponding partition of the DFS by date to obtain the incremental data;
identifying the incremental data in accordance with preset data types;
storing the dimension data in the dimension table sequentially in accordance with lifecycles and an order of change times of the data;
generating the surrogate key in accordance with lifecycles of the dimension data; and
storing the event data in the event table in accordance with the lifecycles and the change times of the data, and a correspondence between lifecycles of the event data and the surrogate keys.
