Abstract

The invention discloses a data processing method and device applied to a data warehouse, and relates to the technical field of computers. The data processing method includes the specific steps that real-time data is received, and historical data related to the real-time data is determined; a file of the historical data is determined, and the real-time data is transmitted to a real-time data layerof the file; a version of the real-time data and a version of the historical data are obtained respectively, real-time data or historical data of the latest version is extracted and serves as the latest data record of the file, and the latest data record is written into a historical data layer for record updating. According to the data processing method and device in the embodiment, combination between a traditional data warehouse and a real-time computing technology is achieved, the ETL timeliness of the data warehouse is improved, and the requirement when a user conducts real-time-data queryanalysis is met; in addition, based on existing off-line data, the development cost of real-time computing of the data warehouse can be reduced, and the business requirement of the data warehouse isbetter met.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data processing method and device applied to a data warehouse. Background technique [0002] With the rapid growth of business data, data warehouse construction has become a key measure to effectively manage and utilize big data for business intelligence and auxiliary decision-making. Usually, a Hive-based data warehouse focuses on offline data processing and mainly supports data services with a timeliness of (T+1). The operation mode of offline ETL (Extract-Transform-Load, extract-transform-load) data warehouse is increasingly unable to meet the user's processing requirements for implementation data. [0003] In the prior art, the solution for realizing the quasi-real-time ETL of the data warehouse is to store the historical data separately from the streaming data files processed by the real-time computing framework. Real-time data and historical data will not be correlate...
