Embodiment Construction

[0018] Such as figure 1 As shown in , the system collects metadata, and forms the metadata database of the specified system by configuring the underlying data sources and suspension points. Secondly, screen the data in the metadata database for information islands, that is, extract the primary and foreign key associations collected in the metadata database, and list the information island data that is not linked by primary and foreign keys to form a data flow connection on the front-end page displayed in , prompting the user to modify and improve, and scoring according to the ratio of the number of problem data.

[0019] Next, compare the field name, field type, field length, etc. in the metadata with the data standard dictionary, extract any inconsistent metadata and display it on the front-end UI interface to achieve data standardization assessment. At the same time, according to the problem data The ratio is scored.

[0020] Next is the evaluation of the data content. Fir...

Abstract

The invention discloses a data quality-based data management system. According to the data management system, metadata is collected, and a metadatabase of a specified system is formed by configuring an underlying data source and a suspension point; the data in the metadatabase is subjected to information isolated land screening, namely, a primary and foreign key association relationship collectedby the metadatabase is extracted, information isolated land data forming a data stream connection without assistance of primary and foreign key association is displayed in a list, a user is prompted to perform modification and perfection, and scoring is performed according to a problem data quantity ratio; and field names, field types and field lengths in the metadata are compared with a standarddata dictionary, any piece of unconformable metadata is extracted and displayed in a front-end UI, data standardization condition assessment is realized, and the scoring is performed according to theproblem data ratio.

Description

technical field [0001] The invention belongs to the technical field of data governance, and in particular relates to a data quality-based data governance system. Background technique [0002] The patent document with the publication number CN102012935A discloses "a method of managing data between systems through Excel, ... the method of managing data between systems through Excel provides an automated conversion process in the form of an Excel plug-in to Solve the problem that users are extremely difficult to convert data between systems. The specific method involves accessing Excel tables, source systems and source data to be governed in them, target systems and target data that meet their requirements. It includes five processes: exporting data, Loading templates, data conversion, data validation, formatting". [0003] However, in the field of data governance, there has not been a complete plan on how to evaluate the quality of data governance and how to improve the quali...
