MongoDB vs CouchDB : Which is Better?
MongoDB VS CouchDB
CouchDB is known for its strong ACID compliance and easy replication, making it suitable for distributed systems, while MongoDB offers high performance and flexibility with its rich query language and sharding capabilities. The choice between the two largely depends on the specific needs for consistency, scalability, and the complexity of operations.
