What's your favorite database

MySQL definitely!

Mongodb. Because it can be easily used with Applications which has dynamic behaviour. But those databases do the same thing in different ways.

Of course ORACLE...

In case I need a DB to scale, Cassandra for being able to deliver outstanding performance over processing huge amounts of data, for small projects im fine with PostgresSQL

SAP Hana.. the fastest database alive!

SQLite

sql

Now SQL
