Embodiment Construction

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

[0055] Some terms involved in the present invention and their explanations 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, and upstream and downstream relationships are used as a kind of metadata to describe the upstream and downstream relationships between data;

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

[0060] Hive: A Hadoop-based data warehouse tool that can map structured data files into a database table and provide simple SQL query functions, which can convert SQL statements into MapReduce tasks for running.

Abstract

The present invention provides a metadata processing method, comprising the following steps: obtaining the associated fields between a target data table and different associated data tables; obtaining the associated information between the target data table and different associated data tables according to the associated fields, and constructing The associated information collection of the target data table; obtain the processing task information of the target data table; according to the processing task information, determine the upstream and downstream relationships between the target data table and different data tables, and determine the upstream data table of the target data table based on the upstream and downstream relationships and the downstream data table; 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 present invention also provides a metadata processing apparatus, device, and readable storage medium. The invention solves the technical problem that the metadata service in the existing database scheme is limited, which makes it difficult to effectively participate in the specific application of the database.

Description

technical field [0001] The present invention relates to the field of computer technology, and 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 the existing database solution, generally only a small amount of metadata is captured, for example, only the table structure information of the system table 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; the existing solution also supports the business meaning of manual maintenance of 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 what further application of these resu...
