  • Publication number: 20230126509
    Abstract: A database management system for performing a graph query based on one or more graph views of a relational-graph database is disclosed. The database management system is configured to determine a plurality of graph views of the relational-graph database based on one or more previous graph queries of the relational-graph database to obtain a plurality of candidate graph views of the relational-graph database. Moreover, the database management system is configured to store a subset of the plurality of candidate graph views of the relational-graph database and perform a graph query of the relational-graph database based on the subset of the plurality of candidate graph views of the relational-graph database. By means of the selected subset of the plurality of candidate graph views of the relational-graph database, the database management system advantageously allows increasing the processing speed of graph queries.
