![]() Others will be ‘native’ GDBs – where the whole construct of the database from storage, management and query maintains the graph structure of the data. Some GDBs may use more traditional database constructs, such as table-based, and then have a graph API layer on top. The storage mechanism used can vary from database to database. They are designed to store and retrieve data in a graph structure. Graph databases are a type of “Not only SQL” (NoSQL) data store. What is a Graph Database?įirst of all, before we dive into what a graph database is, let’s define the term. ![]() If you’d like to have a play with the example walkthrough movie data set before reading the article (or during!), you are more than welcome to do so. Talk through the more interesting queries that appear in the movie example, and break out exactly what is happening.Compare and contrast some queries, based on either Cypher (for GDB) or SQL.Look at the movie data set, and compare and contrast data models from a GDB and a RDBMS perspective.Take a conceptual look at the differences between relational and graph paradigms.Introduce graph databases, briefly covering the two models that exist.Inspired by a small movie data set used by Neo4j as a guided introduction to graph querying, we are going to look at side-by-side examples and equivalents of what a data model or query would look like in both a graph database, and a relational database. In this article we’re going to cover exactly what they are, and how they compare to the more traditional, Relational Database Management Systems (RDBMS) which have been the stalwart software application of the past 40+ years. Some of you reading on may have heard of graph databases (GDB), some you perhaps haven’t. If you want to find out more about the kinds of problems graph databases help solve, and how you might spot a good application for one, here's an introductory blog post. With ever-larger amounts of data from many different sources, it's critical to be able to understand the data and see how it's all connected. Graph databases are growing in popularity and adoption. Want to drive right in and have a go yourself? Please do! You’ll find instructions on how to get up and running here. It is based on the built in dataset and guide available on the Neo4j Sandbox. In this article, you'll discover of the power of graphs by working with a small movie data set. If you're curious about graph databases and how they compare with relational database management systems, then this beginner-friendly guide is for you.
