Abstract

The invention discloses a data extraction method from mongoDB to mysql based on json, and relates to the technical field of data extraction. The method comprises: loading and storing configuration information of a mongoDB database through a UGetMOongoPlus processor, and reading data from the mongoDB database by executing an sql query statement; outputting the data in the json format into a queue;loading and storing the json conversion configuration information through a MongoMappingProcesor processor, and storing the json conversion configuration information through the MongoMappingProcesor processor; mapping the data in the json format to a mysql data table field; and loading the mysql connection configuration information, the data information and the data table information of the relational database through a ULoadProcesor processor, and storing the json format data into the mysql database. According to the method, the transfer information of the page configuration data from mongoDBto mysql is visualized, and the method is simple, visual, convenient and rapid. The data flows from the source mongoDB to the target mysql database in a json format. Operators do not need to write command lines, sql scripts or shell scripts, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of data extraction, in particular to a data extraction method from mongoDB to mysql based on json. Background technique [0002] With the continuous increase of mongoDB non-relational database in software applications, the use advantages brought by document storage have been recognized by more and more programmers and companies, and mongoDB has been widely used; and there are many scenarios using relational databases to show The advantages of business data cannot be replaced by mongoDB. Therefore, there is a transfer of data from the mongoDB database to the relational database mysql; in addition, many original business systems are built on the mysql database, and there is also a need to transfer from the mongoDB database to the mysql database. [0003] As shown in Figure 11, the common technical solution for transferring data from the mongoDB database to the mysql database is to first export the data in the...
