Big data refers to a large amount of data that cannot be stored and manipulated using traditional DBMS. Big data has three main properties: volume, velocity and variety. Here, the volume refers to the amount of data, velocity refers to the generation of the speed of data, and variety refers to the data type. The alternative to storing big data is to use non-relational databases (NoSQL). Couchbase and MongoDB are two such NoSQL databases.

What is Couchbase
Couchbase is an open source, distributed multi-model NoSQL document-oriented database. It allows multiple users to access it at the same time. The user can perform various operations, such as creating, storing, retrieving, aggregating, manipulating, and presenting data in this database. Couchbase server provides key value or JSON document access with low latency and high sustained throughput. It is capable of clustering it from a single machine to a set of multiple machines. Furthermore, the Couchbase server provides client protocol compatibility with Memcached.
In overall, Couchbase helps in developing and deploying web, mobile and Internet of Things based application. Large popular companies such as Cisco and AOL use Couchbase server.
What is MongoDB
MongoDB is a cross-platform, document-oriented database. It stores data in a form similar to JSON documents with a schema. MongoDB document is a set of key-value pairs while a collection is a set of documents. A document within a collection contains different fields. Content and size of a document can change from one document to another. Thus, it results in MongoDB having no schema.
Another advantage of using MongoDB is that there are no complex joint operations in MongoDB. Also, it provides fast data accessing capabilities. Furthermore, the programmer can use document-based query language to execute dynamic queries on the database.
Difference Between Couchbase and MongoDB
Couchbase or Couchbase Server is an open source, distributed, multimode NoSQL document-oriented database that is optimized for interactive applications. On the other hand, MongoDB is a cross-platform, document-oriented database program. Thus, this is the basic difference between Couchbase and MongoDB.
Couchbase Inc. developed Couchbase, whereas MongoDB Inc developed MongoDB.
Installation and Configuration
Furthermore, Couchbase contains an integrated admin console and configures everything in a single place, whereas MongoDB follows the master-slave principle and requires more manual configurations. Hence, this is also a difference between Couchbase and MongoDB.
Structure and Format
Also, memory is another difference between Couchbase and MongoDB. Couchbase uses one of the high-performance caches and avoids the requirement of external cache while MongoDB requires the use of third-party caches to handle more users and to support scalability.
In Couchbbase, the user can perform maintenance tasks using tools such as Web UI, Command-line Interface (CLI) or REST API while MongoDB usually supports only CLI tools for maintenance, but sometimes it is possible to use third part UI tools.
