What can be stored in NoSQL database?
NoSQL databases store data in documents rather than relational tables. Accordingly, we classify them as “not only SQL” and subdivide them by a variety of flexible data models. Types of NoSQL databases include pure document databases, key-value stores, wide-column databases, and graph databases.
What type of NoSQL database is Cassandra?

What are the similarities between MySQL and Cassandra?
MySQL and Cassandra have a few similarities: Popularity: Both of these open-source databases enjoy high popularity. Deployment: You can deploy MySQL on cloud and on-premises, and it’s the same with Cassandra. Community support: Both MySQL and Cassandra enjoy robust community support.
