It supports a broad spectrum of use cases, from real-time exploratory and predictive analytics to parallel data processing. Again, if an application's data needs agility, scaling, and high performance, MongoDB is the best solution. Those who are into Big data analysis can also use MongoDB. But NoSQL database management systems embrace a wide range of file systems storing structured, unstructured, semi-structured, and polymorphic data.Features of NoSQLNoSQL databases do not follow the relational model. They are schema-free, or they do not follow any specific schema. NoSQL renders heterogeneous data structures (graph, tree, column family, key-value pair, document, etc.) on the same domain. Data is not stored flat in rows and columns (table). NoSQL does not demand data normalization and object-relational mapping. NoSQL does not demand setting up complex concepts like joins, referential integrity, ACID properties, etc. Who should use MongoDB?Developers who want to deal with structured, semi-structured, or unstructured data need to use MongoDB for their applications. Traditional RDBMS (like SQL) uses simple queries to store and retrieve textual data.

But with the advent of big companies like Facebook, Google, Amazon, etc., huge volumes of data are generated, because of which NoSQL databases have become popular. Websites like Google, Twitter, Amazon, Facebook, Instagram, etc., collect terabytes of data every day.Earlier, web applications were simple and did not generate such huge amounts of data. We use NoSQL databases for real-time web apps, mobile apps, big data, etc. It means such databases do not have a fixed schema, but are intended explicitly for the distributed data that demands humongous data storage. It models the data by means other than the tabular relations.

In the year 1998, Carl Strozz introduced NoSQL. This database system came into action in mid-2000.What is NoSQL and why should we use NoSQL?NoSQL stands for Not Only SQL or non-SQL and is an unstructured database that helps store and retrieve data. Documents are a combination of key-value pairs that form the basic unit of data in MongoDB. Here the data and records are stored as documents that behave more like JSON objects. It is a document-oriented database system that belongs to the family of NoSQL (non-SQL). Roy MongoDB is one of the most popular unstructured database management systems that can store a high volume of data. How to Install MongoDB on a Mac By Gaurav Kr.
