I am currently using Couchbase, and wanted to know what are the main differences between Couchbase and MongoDB?

When do you choose Couchbase and when do you choose MongoDB?

CodePudding user response：

In general they should work similar. Here are some comparisons:

• Compare MongoDB vs. Couchbase by MongoDB
• Couchbase vs. MongoDB by Couchbase
• System Properties Comparison Couchbase vs. MongoDB

Some neutral differences:

MongoDB has the bigger user base, it is the most used NoSQL database. Thus you have more drivers and applications for MongoDB than for Couchbase.

When you like to migrate an application from RDBMS (e.g. MySQL or Oracle) to NoSQL (e.g. MongoDB) then it is usually not a smart way to convert each table/column to collection/field one-by-one. In contradiction to Couchbase, MongoDB has limited support for joins but some NoSQL databases don't provide joins at all! NoSQL works different, and as a developer you have to think different.

Couchbase tries to apply SQL language and relational RDBMS functions to NoSQL JSON documents. Couchbase looks more like a "RDBMS - NoSQL Hybrid", it tries to join the good sides from RDBMS to NoSQL (but of course is also takes over the disadvantages from RDBMS)

If you are familiar with SQL and if you are not willing to learn a new query language then Couchbase might be an option for you. If you like to get the full document oriented NoSQL flash, then go for MongoDB.

Just a note: comparisons like above are often outdated and/or not complete. For topics which vital for you, consult their documentation accordingly.
