Problems solved by technology

However, both of the above use a centralized single-node model to build a data warehouse. This type of data warehouse has poor scalability.
With the rapid expansion of the current scale of enterprise data, some of which have reached the level of TB, the above-mentioned traditional data warehouse is increasingly unable to meet the needs of use
[0005] In addition, most of the existing data warehouses focus on multi-dimensional analysis of data, and have limited support for knowledge discovery based on data mining technology, which cannot meet the needs of enterprises to mine valuable information from massive data.

Abstract

The invention discloses a cloud data warehouse system for supporting mass data processing and providing a data mining service, a multidimensional analysis service and a data presentation service. The cloud data warehouse system mainly comprises a main control module, a data loading module and a data mining module, wherein the main control module is used for sending instructions to other application modules and controlling the flow direction of data stream; the data loading module is used for loading data from an external database; and the data mining module is used for carrying out data mining calculation on the data. The cloud data warehouse system further comprises a multidimensional analysis module for carrying out multidimensional analysis on the data and a data presentation module for presenting the data by means of making reports.

Description

technical field [0001] The invention relates to the technical field of data warehouses, in particular to a cloud data warehouse system. Background technique [0002] As the amount of processed information continues to increase, enterprises need to process massive amounts of information from multiple angles and obtain information that supports decision-making. At this time, the transaction-oriented operational database seems to be unable to do what it wants, and the data warehouse technology that integrates a large amount of data oriented to the subject emerges. A data warehouse is a subject-oriented, integrated, relatively stable data collection that reflects historical changes and is used to support management decisions. The data warehouse will integrate data from multiple systems, and then perform data analysis and analysis according to different themes. Results are used to support decision making. [0003] Cloud computing technology is a new type of business platform, w...
