Hi everybody
I have 3 sites which want to be updated as soon as the other one
updates its data.(in 5 seconds)
So I have chosen multimaster solution,sync regardless of the resource concideration.

1-what is the difference between multimaster async and updatable materialized view regardless of resource consuming in multimaster?because in both of them each site can receive and also propagate the data...
I just know that in materialized view we can work offline and then apply it manually is there any other thing?

2-I can not understand the difference beteen multimaster sync and async (considering the 5 seconds,because 5 second is a little time)I mean in this case are they different from each other or not

Also if you think I should use the better solution please let me know?

Thank you inadvance

If you have only one master site and remain thing materialized view site then go for Advanced Replication or If you have more then one master site you can implemetn Multimaster Replication.

I sugges to implement ASYNC mode; becuase if network down between master and materialized site nothing will happen. In Sync mode entire transaction rollback.

Nothing; You need to implement Conflict Resolution between master and materializd view site for Updatable Materializd viws..
