MongoDB has two main types of databases

Single Document Databases:



Single document databases store data in individual documents in a JSON-like format. These databases are ideal for small to medium-sized applications that require a simple data model with a few collections. Single document databases are easy to set up and maintain, and they offer fast read and write performance.











Multi-Document Databases:



Multi-document databases store data in collections of documents in a JSON-like format. These databases are ideal for large-scale applications that require a more complex data model with many collections. Multi-document databases offer powerful querying and indexing capabilities, making them suitable for data analysis and business intelligence applications. However, they require more effort to set up and maintain than single document databases.
