Difference between Couchbase and PostgreSQL
1. Couchbase :
Couchbase Server is an open-source, distributed multi-model NoSQL document-oriented database software package that is optimized for interactive applications. It is also known as Membase. It was developed by Couchbase, Inc. and initially released in August 2010.
2. PostgreSQL :
PostgreSQL is a powerful, open-source Object-relational database system. It provides good performance with low maintenance efforts because of its high stability. It was the first DBMS that implemented multi-version concurrency control (MVCC) feature.
