Based on license revenue it's actually Oracle and MS SQL server by miles. They are currently #1 and #3 on DB-Engines.com. (https://db-engines.com/en/ranking https://db-engines.com/en/ranking) MySQL is #2. PostgreSQL is #4, though it's pretty far back from the first three.
- marcolussetti 8y agoMaybe I'm confused, but ranking databases on license revenue will inevitably show that the databases that charge licenses are higher. I mean PostgreSQL is open source, and required no license fee. I'm not sure that license revenue is a good comparison metric.
- hodgesrm 8y agoDBMS Engines uses a set of metrics that does not include revenue. See https://db-engines.com/en/ranking_definition https://db-engines.com/en/ranking_definition for more. Oracle and MS SQL Server have consistently ranked highly there for many years.
- killbrad 8y agoYou know MySQL, MariaDB, and Postgres don't have licensing costs, right?
- hodgesrm 8y agoOf course. I've worked in and around the OSS DBMS market for over a decade. But the numbers were really big. It seems to me that out of a 2015 US $30B DBMS market Oracle and MS were collecting something like US $29B. The rest of the market,which included products like MongoDB and Cassandra was close to a rounding error. (I don't have the Gartner report handy, sorry.) It's popular on HN to focus on OSS products, but there's a very large proprietary RDBMS market measured both in terms of revenue as well as users. That's how Oracle and MS got to be the behemoths they are today.
