Difference between Neo4j and MariaDB

1. Neo4j : 
Neo4j is most famous graph database management system and it is also a NoSQL database system developed by Neo4j, Inc. Neo4j is different from Mysql or MongoDB as it has its features that’s makes it special compared to other Database Management System. Neo4j stores and present data in form of graph not in tabular format or not in a Jason format. Here whole data is represented by nodes and there you can create a relationship between nodes which means whole database collection will look like a graph, which makes it unique from other database management system.

MariaDB is one of most popular open-source relational database management system (RDBMS). It is developed by original developers of MySQL and initially released on 29 October 2009. It has a significantly high number of new features, which makes it better in terms of performance and user-orientation than MySQL. It uses a standard and popular querying language. It runs on different operating systems and supports a variety of programming languages.
