Graph data management has recently received a lot of attention, particularly with the explosion of social media and other complex, inter-dependent datasets. As a result, a number of graph data management systems have been proposed. But this brings us to the question: What happens to the good old relational database systems (RDBMSs) in the context of graph data management?
Do RDBMSs become obsolete or are they still relevant for large-scale graph data management? Do users now need to dump their data from the relational database to a graph database, or can they store and query graphs (with comparable or better performance) from within the relational engine?
