Introduction to MongoDB

When dealing with data, there are two types of data as we know – (i) structured data and (ii) unstructured data. Structured data is usually stored in a tabular form whereas unstructured data is not. To manage huge sets of unstructured data like log or IoT data, a NoSQL database is used.

• MongoDB is an open-source NoSQL database written in C++ language. It uses JSON-like documents with optional schemas.


• It provides easy scalability and is a cross-platform, document-oriented database.


• MongoDB works on the concept of Collection and Document.


• It combines the ability to scale out with features such as secondary indexes, range queries, sorting, aggregations, and geospatial indexes.


• MongoDB is developed by MongoDB Inc. and licensed under the Server Side Public License (SSPL).
