This document compares NoSQL databases including Cassandra, MongoDB, and Neo4j. It discusses the differences between SQL and NoSQL databases, and provides brief overviews of Cassandra as a wide column store, MongoDB as a document database, and Neo4j as a graph database. The comparison examines features like scalability, data structure, and data replication across different NoSQL databases.
