MongoDB supports several types of databases, including
Standalone: A standalone MongoDB database is a single instance of the MongoDB server that runs on a single machine. It is the simplest type of MongoDB database and is ideal for development and testing environments.
Replica Set: A MongoDB replica set is a group of MongoDB servers that replicate data between each other. It provides high availability and automatic failover in case one of the servers goes down.
Sharded Cluster: A sharded MongoDB cluster is a distributed system that scales horizontally by partitioning data across multiple servers, or shards. It is designed to handle large amounts of data and high write loads.
In-memory: An in-memory MongoDB database is a type of database that stores data in memory instead of on disk. It provides extremely fast read and write performance, but is limited by the amount of available memory.
Mobile: MongoDB also supports mobile databases, which are designed for use in mobile applications. They are lightweight and optimized for low-power devices, and can synchronize data with a backend MongoDB server.
