The most famous NoSQL document-oriented databases namely CouchDB and MongoDB have been discussed in this paper. CAP theorem is being discussed for MongoDB and CouchDB. Map-Reduce is a parallel and distributive programming paradigm for processing bulk amount of heterogeneous and unstructured data on clusters of computers. Map-Reduce operation has been implemented in MongoDB and CouchDB. MongoDB uses map-reduce to perform aggregation. CouchDB uses map-reduce for querying and implementing views. The paper also presents major differences and use cases of both the databases. It is found that MongoDB is better-suited document-oriented database for today's web applications than CouchDB.
