Extending Graph Databases With Relational Concepts

Abstract

Today we have to deal with large amounts of data, and for large amounts of interconnected data, graph databases represent an excellent choice. However, some concepts that are used in relational databases are still not supported in graph databases, and this could hinder their wider use. In this article, how relational database concepts have been successfully transferred into graph databases, including integrity constraint support, inheritance, trigger specification, new visual query languages, etc., is demonstrated.
