MongoDB

MongoDB is a leading open source NoSQL database, highly scalable and performance oriented. Unlike traditional relational databases, the dataset does not have a strictly defined structure, but stores properly indexed documents of various types of any structure. Data is stored and returned as JSON documents, which allows applications to process it more naturally, while retaining the ability to create hierarchies and indexes. MongoDB and AWS DynamoDB analogs are very fast and efficient database engines that work well wherever there is a need to store data with a complex and not always fixed structure.
