Data element vault composed of data warehouse and data element warehouse

Abstract

The invention discloses a data element vault composed of a data warehouse and a data element warehouse, and the data element vault composed of the data warehouse and the data element warehouse comprises the data warehouse which is used for storing data, wherein the data cannot be output from the data element vault; and the data element warehouse which is used for storing the data elements, wherein the data elements comprise the element models and the element results, and the element results are the data sets used for outputting the data element vault after the data are processed by the element models. According to the present invention, the data element vault is constructed based on the data element warehouse and the data warehouse, so that the data in the data warehouse cannot be output from the data element vault, the data can be available and invisible, the data management is enhanced, and the data security is further improved.

Description

technical field

[0001] The invention relates to the field of computer information technology, in particular to a data element treasury composed of a data warehouse and a data element warehouse. Background technique

[0002] 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 time-varying.

[0003] Since the development of the data warehouse, it has partially solved the problems of cross-domain dispersion of data, different data standards, low value of data assets, and weak data asset management. However, the data stored in the data warehouse environment is still raw data.

[0004] In this context, if the data in the data warehouse enters the data element market, because the stored data is original data, if the circulating data...
