Abstract

The invention provides a database migration method and a device thereof. The database migration method transfers a relational database to a graphic database in an automated manner. The database migration method in one embodiment comprises the following steps: aggregating constraint conditions of a referencing table, the referencing table being a table with columns which are set as foreign keys in a table of the relational database, the relational database being used as a migration source database; determining the relationship types of each referencing table by the constraint conditions of each referencing table; a database migration device determining a node generation table corresponding to the referencing table and a relation frame based on the relationship type of the referencing table; and converting each row data of the node generation table to nodes of the graphic database which is used as a migration target database, and according to the relation frame, generating relations of the graphic database, used to connect the generated nodes.

Description

technical field [0001] The invention relates to a database migration method and a device thereof. In more detail, it relates to a method and device for migrating a relational database (relational database) to a graph database (graph database). Background technique [0002] A database migration represents an operation for storing data stored in a database of a first form to a database of a second form. [0003] A relational database is a collection of data items composed of a series of normalized tables, and its data can be accessed or combined in various ways even without reorganizing the database tables. Much of the existing data is managed through relational databases. [0004] A graph database manages data in a manner that defines entities and relationships between entities. There is increasing interest in graph databases capable of quickly retrieving relational information between data like data for social networking services. It is well known that graph databases ca...
