MongoDB is an open-source, cross-platform document-oriented database program written in C++, and developed by MongoDB Inc. It is a document-oriented database that uses JSON like document to store the record, data is stored in key-value pairs. MongoDB is used to store high volume data in high-performance enterprise application, where it provides high performance, availability, and scalability. MongoDB is a NoSQL database, it means you need not to specify schema beforehand. Instead, you can create fields on the fly.
MongoDB is used as database component in MEAN software stack, using a document-oriented database such as MongoDB allows you to work with JSON-like documents for your entire development stack.
