What does the graphical database mean?
A graphical database is a type of NoSQL database that stores data in collections of nodes and edges instead of a series of columns and rows. Each node represents a data point and each edge defines a relationship between two nodes.
Graph databases use graph theory models to illustrate how data points are related. This type of database is useful for storing data that has complex and indirect relationships and for querying the shortest path between two data points.
Techopedia explains the graph database
A graph database uses graph theory to store, map, and query relationships. Essentially, it is a collection of edges and nodes, with each node representing an entity such as a person or organization, and each edge representing a connection or relationship between two nodes.
A node is defined by a unique identifier and has multiple edges attached to it, whether inbound or outbound, and it has a set of properties that are expressed as key-value pairs. An edge is also defined by a unique identifier and has a start and end node, as well as a set of properties.
A graph database is useful for analyzing relationships and interconnections between data; therefore, it is widely used in social media data mining, for data with dynamic schemas, such as in supply chain management, as well as in sales, where it is used to determine interconnections between a customer’s online actions.
