Sometimes it’s just important to store the data and complex analysis isn’t needed. If the connections within the data are not the primary focus and the data is of a transactional nature, then a graph database is probably not the best fit. Graph solutions are focused on highly-connected data that comes with an intrinsic need for relationship analysis. Here are three simple questions you can ask yourself to decide if there are any benefits of using a graph database. There are a lot of use cases for which you should stick with relational databases or maybe search for other alternatives aside from graph databases. There are always two sides to every story and graph databases aren’t a perfect solution for every problem. A relational database isn’t suited for this specific use case because the focus isn’t on the data itself but rather on the relationships within it. If there were different kinds of connections ( related to, no longer friends…) we would have to change the schema accordingly. While this is also pretty straightforward, it’s much more rigid than the graph schema and not as extendible.įor example, each person is connected to other people through friendships, and to model this relationship, we have to add another table. We create one for each entity and add the needed attributes as columns. The Relational Data ModelĪ relational database requires a predefined and carefully modeled set of tables. To be fair, this can cause problems for you in the long run, but you can do it if need be. A property that was meant to be a string can be used as an integer without any constraints. Unlike a table, where you need to add a column for each additional attribute, here you can be much more flexible with the data structure and types. For example, you could easily add different properties to some of the nodes if you wanted to. While this is a very simple example, it concisely demonstrates the power and benefits of using a graph database. The relationships between people in this network are of the type FRIENDS_WITH and contain a yearsOfFriendship property to specify the duration of the friendship connection.Įach person is assigned a location through :LIVES_IN relationships with nodes labeled Location. ![]() These nodes contain the properties name, gender, location and email. Every person is represented with a node that’s labeled as Person. In a typical social network graph, the nodes represent people in different social groups and their connections with one another.
