relational databaseīoth types of databases offer advantages to users, but deciding between graph database vs. The most notable differences between a graph database vs. Relational databases require complex joins on data tables to perform complex queries, so the process is not as fast. Relational databases make adding new tables and columns possible while the database is running.Ĭomplex queries typically run faster in graph databases than they do in relational databases. The flexibility of a graph database enables the ability to add new nodes and relationships between nodes, making it reliable for real-time data. The relational focus is between the columns of data tables, not data points.īoth databases make adding new data easy. Relational databases infer a focus on relationships between data but in a different way. The most notable difference between the two is that graph databases store the relationships between data as data. This enables data professionals to make changes to physical data structure that don't affect the logical structure.
Relational databases separate the logical structures of tables and indexes from physical storage structures. For example, one table may contain customer information that relates to information in a different table containing order information. Tables are defined by columns and rows, and each row is identified by a unique key so they can be linked to rows in other tables.Įach individual table also includes a primary key identifying the information found within the table. Relational databases store data in relational tables. They are designed to be scalable and offer flexibility that's hard to find in other databases.
Graph databases are made up of nodes and edges, where nodes represent specific entities, while edges represent the connection between two nodes. What differentiates graph databases from other options is that they document and prioritize the relationships between data. What is a graph database?Ī graph database is a NoSQL database that stores data as a network graph. Each offers different advantages of data models and abilities to connect relationships between data. Graph processing and graph database applications are projected to grow 100% annually through 2022, according to Gartner.Īs graph database adoption continues to grow, it's important to understand the differences between a graph database vs. One of the top choices for NoSQL is a graph database, with enterprise adoption trending for several years now as organizations work to answer increasingly complex questions using complex data.
