Which database has the best support for replication

Question

I have a fairly good feel for what MySQL replication can do. I\'m wondering what other databases support replication, and how they compare to MySQL and others?

Answer 1

All the main commercial databases have decent replication - but some are more decent than others. IBM Informix Dynamic Server (version 11 and later) is particularly good. It actually has two systems - one for high availability (HDR - high-availability data replication) and the other for distributing data (ER - enterprise replication). And the the Mach 11 features (RSS - remote standalone secondary, and SDS - shared disk secondary) are excellent too, doubly so in 11.50 where you can write to either the primary or secondary of an HDR pair.
