Practical Perl Tools: It’s a Relationship Thing

Faithful readers of this column will know I have a declared affection for graphs. In the past, we’ve looked at ways to represent graphs in Perl and ways to draw them. But strangely enough, we’ve never looked at one of the more interesting uses for them these days: as a data representation for a database, that is, graph databases. This column aims to right that wrong. Rather than take on the entirety of the graph database space in this column, we’ll use Neo4j, one of the more popular ones, as a springboard for how they work and how we can interact with them via Perl.
