Method and device for constructing metadata consanguinity map and related equipment

Abstract

The invention discloses a method and device for constructing a metadata consanguinity map and related equipment, and the method comprises the steps: obtaining metadata in a plurality of systems and relation information used for indicating the incidence relation between the metadata in the plurality of systems, the relation information comprises a source system identifier, a source mode identifier, a source data table identifier, a target system identifier, a target mode identifier, a target data table identifier and a service identifier corresponding to different metadata; the relation information is traversed, the relation among a plurality of nodes in the metadata consanguinity map is determined, the nodes comprise system nodes, mode nodes and data table nodes, the nodes correspond to different metadata in the systems, and the metadata consanguinity map is generated according to the nodes. Therefore, the cross-system metadata consanguinity map can be generated, so that the metadata consanguinity map can be utilized to trace the source of the abnormal data and / or determine other data influenced by the abnormal data and the like, and the actual application requirements are met.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method, device and related equipment for constructing a metadata blood relationship map. Background technique [0002] The metadata blood relationship map refers to a map used to represent the blood relationship between metadata, where the blood relationship between metadata may be, for example, an attribution relationship, a derivation relationship, and the like. Metadata refers to data used to describe data, such as field attributes in a database. [0003] At present, when constructing a metadata lineage map, the metadata in a single system is mainly used to construct a metadata lineage map according to corresponding rules, so as to use the metadata lineage map for information management, impact analysis, and traceability. However, this kind of metadata kinship map is difficult to meet the actual needs of some application scenarios. For example, in some ap...

However, this kind of metadata kinship map is difficult to meet the actual needs of some application scenarios

For example, in some application scenarios, there may be multiple business systems running within the company, and there are data and metadata transfers between the multiple business systems. At this time, after the data and metadata in the upstream business system change , it is difficult to determine the data in the affected downstream business system according to the corresponding metadata blood relationship map of each business system; or, it is difficult to trace the abnormal data in the upstream business system according to the abnormal data in the downstream business system, etc.
