Noe4j graph database updating and maintaining method and device and computer readable storage medium

Abstract

The invention relates to a big data technology, and discloses an updating and maintaining method of a Noe4j graph database, which comprises the following steps of: obtaining a relational document of the Noe4j graph database, inquiring nodes of graph data in the relational document, calculating an aggregation coefficient of the nodes, and generating an inquiry document of the Noe4j graph database according to the aggregation coefficient; calculating the average path length of any two nodes in the query document, and supplementing the nodes to the query document according to the average path length to generate a supplementing document; correcting the nodes in the supplementary document to generate a corrected document; and analyzing the correction document to generate a linked list relationdocument, and uploading the linked list relation document to the Noe4j graph database to finish updating and maintenance of the Noe4j graph database. The invention further provides an updating and maintaining device of the Noe4j graph database and a computer readable storage medium. According to the invention, efficient updating and maintenance of the Noe4j graph database are realized.

Description

technical field [0001] The present invention relates to the field of big data technology, in particular to a Noe4j graph database update maintenance method, device and computer-readable storage medium. Background technique [0002] The update and maintenance of the Neo4j graph database is generally completed by the technicians based on the data sources provided by the business personnel (including the core concepts of the field and the description of the relationship between core concepts), through data cleaning, sorting, and finally using the data loading method provided by Neo4j. It cannot be directly entered by business personnel, and due to the single method and one-sided observation, this maintenance operation is often limited by the professional level of business personnel, and cannot complete the update task accurately and efficiently.
