What is the basics of MongoDB?

MongoDB basics involve it being a NoSQL, document-oriented database that stores data in flexible, JSON-like documents (BSON) within collections, rather than rigid rows and columns. Key concepts are databases (containers for collections), collections (groups of documents, like SQL tables), and documents (key-value pairs, like JSON objects). It offers dynamic schemas, scalability, and high performance for modern applications dealing with diverse data.
