Problems solved by technology

[0002] Common data traceability models include flow traceability information model, time-value center traceability model, four-dimensional traceability model, etc., but the formation process of these models is not direct, difficult to understand, or established for different angles and certain characteristics, and many Most of them start from the business data level, but cannot really trace the source of the data

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 As shown, a data traceability method based on a non-loop directed graph includes the following steps:

[0022] S1. Positioning and traceability indicators

[0023] Determine the indicators that need to be traced in the business model according to the requirements, and obtain the basic information and logical rule information of the indicators;

[0024] S2. Index decomposition

[0025] According to the logical rules of the traceability index, the decomposition index of the traceability index is obtained, the type of the decomposition index is judged, and the source is traced according to different types. If the logical rule of the decomposition index does not include the decomposition index of the next level, that is, the decomposition index belongs to the entry node , then trace the source directly from the decomposit...

Abstract

The invention provides a loop-free directed graph-based data tracing modeling method, which comprises the following steps: positioning a traceable index; decomposing the index; tracing data; verifying the result; and solidifying the result. A global data tracing view is built by gradually tracing data assets and specifying a key monitoring point and a risk point, so that erroneous data can be quickly analyzed and positioned; tracking in a data transfer process can also be achieved; efficient sharing application of the data is greatly promoted; and a basis is laid for data operation monitoring work. Therefore, the target of improving the quality of the data assets is achieved.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a data traceability method based on a non-loop directed graph. Background technique [0002] Common data traceability models include flow traceability information model, time-value center traceability model, four-dimensional traceability model, etc., but the formation process of these models is not direct, difficult to understand, or established for different angles and certain characteristics, and many Most of them start from the business data level, but cannot really trace the source of the data. Contents of the invention [0003] The purpose of the present invention is to provide a data traceability method based on a non-loop directed graph, complete the data traceability model for the non-loop directed graph, face structured data, use index data as the basis, and use backtracking as a means to form a tree-like The data traceability view realizes the controlla...
