| Oracle | oracledb | npm install oracledb |
| MySQL | MySQL | npm install mysql |
| PostgreSQL | pg | npm install pg |
| SQLite | node-sqlite3 | npm install node-sqlite |
The following table lists important NoSQL databases and respective drives .

| MongoDB | mongodb | npm install mongodb |
| Cassandra | cassandra-driver | npm install cassandra-driver |
| LevelDB | leveldb | npm install level levelup leveldown |
| RavenDB | ravendb | npm install ravendb |
| Neo4j | neo4j | npm install neo4j |
| Redis | redis | npm install redis |
| CouchDB | nano | npm install nano |
The above database list is not limited. There are many other databases and drivers available to be used with Node.js. Also, there are many drivers available for each database. So, choose a driver carefully based on your need.
