Problems solved by technology

[0003] However, the importance of data quality is often overlooked in the process of system construction, and insufficient measures are taken to effectively detect data quality. As a result, with the gradual and in-depth application of the system and data, data quality problems are exposed little by little, such as the validity of data. accuracy, consistency, etc.
The worst result is that users feel that the system and data are untrustworthy, and finally give up using the system, thus losing the meaning of building the system

Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] see figure 1 , the present invention provides a data quality assessment method, the specific process is as follows:

[0027] Step 1, import the database.

[0028] In this embodiment, a database that requires data quality assessment is accessed, and the quality assessment is performed on the data in the database.

[0029] Step 2, filter the data in the database.

[0030] In this embodiment, according to the five dimensions, which data in the database has an impact on the data quality is analyzed, especially which tables have an impact on the data quality, and the data with a large impact on the data quality is preferentially selected for data quality evaluation.

[0031] Step 3, configure evaluation rules.

[0032] see figure 2 , step 3 is implemented through the following process:

[0033] Step 31, determine the proportions of the five dime...

Abstract

The invention provides a data quality assessment method, and relates to the field of data quality management. The proportions of five dimensions reflecting data quality are set; for the dimensions, assessment rules are configured; after the assessment rules are configured, the rules run one by one; rule scores are obtained, so that scores of the dimensions are obtained; and summation is performedto obtain a quality score. The data quality assessment is concisely displayed in a score form, so that the user experience is enhanced.

Description

technical field [0001] The invention belongs to the field of data quality management, and in particular relates to a data quality evaluation method. Background technique [0002] With the development of science, various system applications are becoming more and more complicated, and more and more data need to be processed. Data processing occupies a very important position in the construction and use of various system applications. [0003] However, the importance of data quality is often overlooked in the process of system construction, and insufficient measures are taken to effectively detect data quality. As a result, with the gradual and in-depth application of the system and data, data quality problems are gradually exposed. accuracy, consistency, etc. The worst result is that users feel that the system and data are untrustworthy, and finally give up using the system, thus losing the meaning of building the system. Contents of the invention [0004] In order to solv...
