MongoDB is an open source database that uses a document-oriented data model and a non-structured query language. It is one of the most powerful NoSQL systems and databases around todayBeing a NoSQL tool means it does not use the usual rows and columns that we so much associate with the relational database management. It is an architecture that is built on collections and documents. The basic unit of data in this database consists of a set of key-value pairs.
