What is the use of MongoDB or When to use MongoDB ?

  • MongoDB is mostly used as the primary data store for operational applications with real-time requirements . MongoDB is easy to operate and scale in ways that are hard if not impossible with relational databases.

  • MongoDB may not be a good fit for some applications. For example, applications that require complex transactions  and scan-oriented applications that access large subsets of the data most of the time may not be a good fit for MongoDB.
