How these alternatives were chosen
Tools Microsoft SQL Server names as alternatives that this directory also publishes, followed by others in Database. The order is not a ranking, and "—" means we have not checked that field — not that the answer is no.
Microsoft SQL Server also lists Oracle Database, Amazon RDS as alternatives. Those are not in this directory yet, so there is nothing to compare — and nothing to link to.
