As a PHP developer you are probably used to seeing applications and articles using MySQL or some other relational database management system (RDBMS). But in the past few years, a new kind of database has gained adoption in the software development community. This new type of database focuses on document objects rather than strictly defined records and relationships, and has been nicknamed âNoSQL.â There are a lot of implementations of the NoSQL concept, but one of the most famous and widely used NoSQL databases is MongoDB. I think itâs one of the most interesting NoSQL databases available currently, and itâs considered by many to be one of the easiest to use (which has helped it gain widespread adoption)
