Neo4j : A graph database for social media content

Introduction

Laymen explanation

If you need to create a database which can keep information about your useful items like grocery, customers and also want to know who has purchased what, then you will need a software database. Relational DBMS can serve the purpose if you have predefined attributes.

However considering the case like social media where you can't predefine the attributes, then it will be good to use no-sql Database. Moreover, this DBMS must provide graphical pictorial representation. This will be useful to derive relations among different items. For example, you may want to know which Facebook user has shared your post related to corona-virus precaution
