Abstract

The invention discloses a data dictionary generation method and system, and belongs to the technical field of database management, the generation method comprises: obtaining a data range of a to-be-generated data dictionary, the data range comprising a target database or a data table; obtaining a target structure data table from a corresponding data warehouse server according to the data range; reading structure information from the target structure data table according to the format of a data dictionary; and writing the structure information into the data dictionary. By determining the data source and the data range thereof, the information of the target structure data table is obtained from the data range, and the data dictionary is established according to the target structure data table and the structure data thereof, so that real-time updating and maintenance of the data dictionary are facilitated, and management of the data dictionary is facilitated.

Description

technical field [0001] The invention relates to the technical field of database management, in particular to a method and system for generating a data dictionary. Background technique [0002] A data dictionary is a directory that records database and application metadata that users can access. It defines and describes data items, data structures, data flows, data storage, processing logic, etc. Make detailed descriptions of the various elements in the data flow diagram, using the data dictionary for simple modeling projects. Simply put, a data dictionary is a collection of information describing data, a collection of definitions for all data elements used in a system. [0003] However, at present, most of the data dictionary documents are manually maintained manually, and the data table structure information is read from the database through direct editing or through query statements, and then copied to the document for storage. In the process of database construction, da...
