Some elements of Graph Theory are then very important in the infrastructure used here, in order to correctly connect distant computers together in the best way. Each computer on the Internet - servers, routers, switches - is a Node, and each connection between them is an Edge. ![]() For example, any time you try to use a Tube Map or trace a Family Tree, you are dealing with a Graph.Įven using the Internet on a daily basis is using a Graph. Graphs are already prevalent in the real world, and in software development. This is a branch of Mathematics that deals with the complexities that Graphs can contain, and with how best to get information out of them. Once you start dealing with Graphs, you very quickly get involved in Graph Theory. Conversely, an Undirected Graph would be one where the edges are simply links with no direction associated with them. Each Node represents some piece of information in the Graph, whereas each Edge represents some connection between two Nodes.Ī Directed Graph is a special type of Graph where edges always have a direction associated with them. In Mathematical terms, a Graph is simply a collection of elements - typically called Nodes (also called Vertices or Points) - that are joined together by Edges. Specifically a Graph Database will typically be a Directed Graph. In this context, a Graph Database represents a mathematical Graph. ![]() What is a Graph?īefore we can understand what a Graph Database is, we first need to understand what is meant by a Graph. This article aims to explore exactly what they are and where they can be a good fit in your application landscape. This can allow a large level of flexibility to represent your data in a way that makes the most sense to everyone involved, whilst still making the most of the complex interactions between it. Graph Databases are currently gaining a lot of interest, as they can give very powerful data modeling tools that provide a closer fit to how your data works in the real world. If you are reading this article then no doubt you have already heard of the concept of a Graph Database, and are looking to learn more about what they are and what they can do for you. You may have heard about Graph databases but are they right for you? In this Write Stuff article, Graham Cox looks at the concepts and application of Graph databases.
