Abstract

The invention provides a construction method and system of a data warehouse (DW or DHW) and a server. The method includes: constructing a multi-layer data processing architecture for hierarchical processing on data; extracting needed data from data sources, and cleaning the extracted data to form the data according with preset requirements; scheduling and supervising data processing tasks; and controlling access authority of the data in the multi-layer data processing architecture, and supervising overall running status of the data. The multi-layer data processing architecture includes: a temporary storage layer (ODS), which temporarily stores the data acquired from the data sources; a core data layer, which stores and processes the data after cleaning; a data mart layer (MID), which organizes the data to form corresponding data topics; and an application layer (APP), which is user-oriented to process specific demand data input by a user. The method can quickly construct the enterprisedata warehouse, reduce complexity of warehouse construction, shorten a development cycle of building the data warehouse by an enterprise, and reduce warehouse development and operation and maintenance costs, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to a construction method, system and server of a data warehouse. Background technique [0002] Data warehouse, the English name is Data Warehouse, which can be abbreviated as DW or DWH. A data warehouse is a strategic collection that provides support for all types of data for decision-making processes at all levels of an enterprise. It is a single data store created for analytical reporting and decision support purposes. Provides guidance on business process improvement, monitoring time, cost, quality, and control for businesses that need business intelligence. [0003] A data warehouse is a structured data environment for decision support systems (dss) and online analytical application data sources. Data warehousing studies and solves problems of obtaining information from databases. The characteristics of data warehouse are subject-oriented, integrated, stable and ti...
