# Pros of Cassandra

**Data security.** Due to its master node replication feature, Cassandra stays failure tolerant. It means that DB engineers can feel confident about data safety unless master nodes fail all at the same time. As long as it’s extremely unlikely, the database and the application built on it will stay sound and secure.

**Flexibility and on-hand amendments**. Cassandra’s simple syntax has the best of SQL and NoSQL. In addition to scalability, it largely contributes to dataset flexibility. Cassandra collects data on the go, and data retrieval shares the same simplicity, despite dataset size. This allows for enlarging the database to the fullest extent.
