Abstract

The present disclosure relates to a method and device for drawing a data map. The method includes: acquiring map data in a database and saving it in a local cache, the map data including at least one table relationship; when receiving a request from a user to access a data map, Sending a first access request to a server; receiving feedback information sent by the server to the first access request; updating map data in the cache according to the feedback information, and reading updated map data from the cache ; Draw the data map according to the read map data, thereby improving the efficiency of drawing the data map.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a method and device for drawing a data map. Background technique [0002] At present, based on relational diagram drawing plug-ins, such as data maps, users only need to provide graphics and the relationship between graphics, and the relationship between graphics can be expressed through the plug-in built-in API (Application Programming Interface, application programming interface). to show. [0003] The ETL (Extract-Transform-Load, extract-transform-load) file contains the relationship between tables. Users can obtain the relationship between tables by uploading the ETL file and parsing the ETL file, and then can This relationship is displayed through the data map to realize the drawing process of the data map. [0004] When drawing the relationship between tables based on the data map, it is necessary to request the data of the data map from the database,...
