Embodiment Construction

[0054] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0055] Some terms and explanations thereof involved in the present invention are listed as follows:

[0056] metadata: data used to describe data;

[0057] Metadata association information: the association relationship between metadata;

[0058] Upstream and downstream relationship: also known as "blood relationship". Many data in the information system are processed from upstream data. The upstream and downstream relationship is used as metadata to describe the upstream and downstream relationship between data;

[0059] SQL: a query statement of a relational database;

[0060] Hive: A Hadoop-based data warehouse tool that maps structured data files to a database table and provides simple SQL query functions that convert SQL statements into MapReduce tasks for execution.

[0061] HBase: A distributed columnar stora...

Abstract

The invention provides a metadata processing method. The metadata processing method comprises the following steps: obtaining correlation fields between a target data table and different correlation data tables; According to the correlation field, obtaining correlation information between the target data table and different correlation data tables, and constructing a correlation information set ofthe target data table; Obtaining processing task information of the target data table; Determining upstream and downstream relationships between the target data table and different data tables according to the processing task information, and determining an upstream data table and a downstream data table of the target data table based on the upstream and downstream relationships; Wherein the target data table inherits the association information of the upstream data table, and the downstream data table inherits the association information set of the target data table. The invention further provides a metadata processing device and equipment and a readable storage medium. The technical problem that in an existing database scheme, the meaning of metadata service is limited, and consequentlyit is difficult to effectively participate in specific application of a database is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a metadata processing method, device, device, and readable storage medium. Background technique [0002] In the field of database technology, metadata is related data used to describe data. In existing database solutions, generally only a small amount of metadata is captured, for example, only table structure information of system tables in the database is obtained. This information is only filled in by developers when designing the table structure, and the business meaning is very limited; existing solutions also support the business meaning of manually maintained metadata, but the business meaning of manually maintained metadata is often lagging, incomplete, and incomplete. precise. [0003] In addition, when searching, the existing database only presents the search results, and does not inform the searcher of any further application of these results; the searcher m...
