MongoEngine - MongoDB Setup

NoSQL databases have seen rise in popularity in the last decade. In todays world of real time web applications, huge amount of data is being generated with mobile and embedded devices. Traditional relational databases (like Oracle, MySQL, etc.) are not suitable for strings. The processing of such data is also difficult as they have fixed and predefined schema, and are not scalable. NOSQL databases have flexible schema and are stored in distributed manner on a large number of community servers.

NOSQL databases are classified on the basis of organization of data. MongoDB is a popular Document Store NOSQL database. Fundamental constituent of a MongoDB database is called a document. A document is a collection of key-value pairs stored in JSON format. More than one documents are stored in a collection. A collection can be considered as analogous to a table in any relational database, and a Document as row in a table. However, it should be noted that since MongoDB is schema less, number of key-value pairs in each document of a Collection need not be the same.

MongoDB is developed by MongoDB Inc. It is a general-purpose, distributed document based database. It is available in enterprise as well as community edition.
