Today found an interesting statistics by Jelastic platform on database servers used in November 2011.
As before, MySQL is still the leader. PosgreSQL takes second place of honor, followed by MariaDB. Only one of the NoSQL databases MongoDB showed very good results in November.
If compare current data with the October, we can conclude that the number of fans did not change.
According to the table we need PgConf.eu twice a year. ;)
