Oracle people tend to be heavy oracle people too. At the bank I worked before 2019 at I was on a advanced analytic team, we had this amazing teradata database and then there were these insanely fast (yet older) IBM DB2 databases and then there was a few big oracle databases. We did amazing things with teradata + DB2 and then a leader who was tired of multiple databases asked us to vote, we chose teradata so we went with oracle and the migration was so bad I left.
