Problems solved by technology

[0002] In related technologies, in order to solve the problem of metadata traceability in various special databases, relational databases are generally used to maintain the hierarchical relationship of metadata. In this case, the connection query between tables can be traced back to the business system database; It is suitable for the traceability of metadata within a certain relationship depth range, beyond which the traceability cannot be traced or the traceability efficiency is poor

Abstract

The invention provides a metadata tracing method and device and a server. The method comprises the following steps: after obtaining a data tracing request, determining target metadata corresponding tothe data tracing request according to the data tracing request and a first mapping relationship between a pre-established special database and a preset summarized database; and determining a tracingresult corresponding to the data tracing request according to the target metadata and a pre-established second mapping relationship between a summary database and a service system database. The type of the summarized database established based on the preset business system database is the graphic database, the target metadata corresponding to the data tracing request can be quickly determined in the summary database, then the tracing result can be determined in the business system database according to the target metadata, real-time tracing of the metadata in the thematic database is achieved,and the tracing efficiency is improved.

Description

technical field [0001] The invention relates to the field of databases, in particular to a metadata tracing method, device and server. Background technique [0002] In related technologies, in order to solve the problem of metadata traceability in various special databases, relational databases are generally used to maintain the hierarchical relationship of metadata. In this case, the connection query between tables can be traced back to the business system database; It is suitable for the traceability of metadata within a certain relationship depth range, beyond which it cannot be traced or the traceability is inefficient. Contents of the invention [0003] In view of this, the object of the present invention is to provide a metadata traceability method, device and server, so as to realize real-time traceability of metadata in a thematic database and improve traceability efficiency. [0004] In the first aspect, an embodiment of the present invention provides a metadata ...
