Open source databases: What are they and why do they matter?

Wrote about the topic of picking an open source license in length:

Apache 2.0 is the dominant license at this point, mainly because to foster adoption.

The whole scare about the clouds ripping you off, like it happened with Elastic, is not really valid anymore. The clouds have learned that it's better to cooperate.

Commercial databases are expensive and you have to buy a license for each client. Not so with open source databases. If costs is critical use a free and open source database like PostgreSQL or MySQL.
