Comparison between MongoDB vs. Cassandra

In this article we will discuss about similarities and differences between MongoDB and Cassandra.
1. MongoDB :
MongoDB is a cross-platform document-oriented database program. It is an open-source document database, which stores the data in the form of key-value pairs.

Supported Languages : C++, Go, JavaScript, Python.

2. Cassandra :
Cassandra is a free and open-source, distributed, wide column store, NoSQL database management system. Which is used to handle large amounts of data.

Supported Languages : Java

Similarities :

1. MongoDB and Cassandra used TCP/IP Protocol to transfer/receive the data through a network.
2. Locks are available in Both.
3. Both will support Linux OS, Mac – OS and Windows
4. Both will store the data in disc.
5. MongoDB and Cassandra are open sourced(Freely available to all)
6. Both are scalable
