When I first encountered the idea of labeled property graph data storage, I thought about the Dirk Gently Holistic Detective Agency series — where a belief in the fundamental interconnectedness of things plays a central role to the plot. Traditional SQL storage stored information and relationships were defined by cross-referencing a field (or more) between tables. The creators of graph databases sought to store the relationships along with data elements.<\/p>\n

A labeled property graph database store nodes<\/em> \u2013 the circles below \u2013 and define relationships \u2013 the lines \u2013 between nodes. Relationships are a way to show the interconnectedness of all things — people who purchased items, individuals who acted or directed films. I am looking at graph databases to maintain plant hybridization records — relationships build the family tree.<\/p>\n

Nodes can have a label \u2013 essentially a classification, here I have \u201cCandidate\u201d nodes and \u201cElection\u201d nodes. A node can have multiple labels — maybe a political party affiliation as well as candidate. Nodes can include relationships to themselves (I’ve met me?)<\/p>\n

Relationships have a type \u2013 WON or LOST here. Relationships are also directional \u2013 an election didn\u2019t win a dude, a dude won an election.<\/p>\n

Both nodes and relationships can have properties \u2013 additional information about the entity. In this example, each election node stores a year in which the election took place along with the vote totals both popular vote and electoral college results.<\/p>\n
