Abstract

The invention discloses a method for model conversion and data migration of Neo4j to a relational database. The method comprises the steps that at the step S1, a conceptual model of the Neo4j is extracted; at the step S2, a user screens label entities and relation entities to be converted; at the step S3, all the relation entities containing attributes are sought, and all the relation entities containing the attributes are converted into a table in the conceptual model of the relational database; at the step S4, all the label entities to be converted are converted into a table in the conceptual model of the relational database; at the step S5, relation attributes which can express relations among each table in the conceptual model of the relational database are established; at the step S6, a complete conceptual model of the relational database is established; and at the step S7, the data migration is carried out. According to the invention, the model conversion method is adopted to solve problems in the data migration of the Neo4j to the relational database; and the data migration becomes more accurate and can be operated more easily.

Description

technical field

[0001] The invention relates to the technical field of computer databases, in particular to a model conversion and data migration method from Neo4j to a relational database. Background technique

[0002] In the early days of data modeling, there were two main schools. One was the relational model, which gradually evolved into a relational database; the other was the network structure adopted by the semantic network, which has now evolved into a graph database in non-relational data. The most popular and representative database in graph database is Neo4j.

[0003] Neo4j is a high-performance, world-leading graph database with a flexible structure and complete transaction features. Compared with relational databases, Neo4j has its own advantages and disadvantages. The advantage of Neo4j is that it saves all the data in the network rather than in the form of tables in relational databases, so it has good query speed and is especially suitable for expressing re...
