Abstract

Much of the data found in practice resides in relational DBs. However, many contemporary analytical tasks are performed on graphs. Property graphs are currently one of the most prevalent data models for graph data management in industry. Therefore, a key challenge is to understand the fundamental relationships between relational databases and property graph databases. This paper reports our ongoing work towards understanding these relationships by proposing R2PG-DM, a direct mapping of relational databases to property graphs. Given a relational database schema and instance, a direct mapping generates a corresponding property graph instance. The semantics of our mapping is defined using Datalog. Our work is inspired by existing approaches for direct mappings of relational databases into earlier graph data models. Future work is to study our mapping with respect to fundamental properties such as information and query preservation.
