Yellow River water and sediment change data warehouse

Abstract

The invention relates to a Yellow River water and sediment change data warehouse which comprises a data source, a convergence layer, a storage layer and an application layer which are sequentially connected from bottom to top, and the data source is located at the bottommost layer, is composed of structured data, semi-structured data and unstructured data and is used for realizing aggregation of source data to the convergence layer; the convergence layer is used for extracting required data from the data source, processing the data and transmitting the processed data to the storage layer; thestorage layer is used for storing the data processed by the convergence layer; and the application layer is a tool for a user to access data and is used for performing data analysis on the data. The data warehouse provided by the invention can completely and uniformly describe each item of data involved in each analysis object and the relationship between the data, and the application data analysis is multi-angle, multi-view mode and rotatable. According to analysis requirements, a large amount of data can be rapidly and flexibly processed, and query results can be provided for various decision makers in a visual and understandable mode.

Description

technical field [0001] The invention belongs to the technical field of software architecture, and in particular relates to a data warehouse for water and sediment changes in the Yellow River. Background technique [0002] Decision-making on any major issue needs to have a large amount of relevant data as support, and then help users quickly obtain sufficient decision-making information from it. For the various data involved in water resource management in river basins, it is necessary to analyze various types of data and the relationship between various types of data. Scientific and effective decision-making can only be made after analyzing the interrelationships. [0003] In related technologies, with the development of communication technology, water resources have higher requirements for the speed and accuracy of data acquisition. But there is no better way to store and manage data. Contents of the invention [0004] In view of this, the purpose of the present inventi...
