Many people thought that the acquisition of MySQL by Oracle was going to kill the prospect of an open-source database. In fact, a recent study suggests that most MySQL users are either neutral or positive about where the database is headed. Of the 130,000 surveyed by Jaspersoft, 47% werent thinking of switching databases and only 5% said that they planned to, PostgreSQL being the most likely candidate. Also, 19% thought it was still too early to make a decision regarding a switch. And an interesting 22% said they would tend to use MySQL more now because Oracle owns it.
As far as the improvements coming, 43% said they thought MySQL development would improve, 35% said it would stay the same, and 22% said it would suffer under Oracles watch.
