Question

What is the difference between couchbase and mongodb?

Answer 1

Couch Base and MongoDB are both Document Based NoSQL Database but they have some differences:

1. Data Model: For Data Modelling MongoDB used BSON which is a format very similar to JSON while CouchBase purely includes a JSON structure. 

2. Concurrency: The couch base server is both optimistic as well as pessimistic locking while the MongoDB server is also both optimistic as well as pessimistic locking but with an optional store machine called the WiredTiger.

3. The Couchbase server has the capacity to store binary values to about 20 MB, but the MongoDB server has got the ultimate capacity of storing huge files into a vast number of documents.
