Graphs are ubiquitous. Social or P2P networks, thesauri, route planning systems, recommendation systems, collaborative filtering, even the World Wide Web itself is ultimately a graph! Given their importance, it’s surely worth spending some time in studying some algorithms and models to represent and work with them effectively. In this short article, we’re going to see how we can store a graph in a DBMS. Given how much attention my talk about storing a tree data structure in the db received, it’s probably going to be interesting to many. Unfortunately, the Tree models/techniques do not apply to generic graphs, so let’s discover how we can deal with them.
