Will Replication Help me with this?

[Edson Luiz Q. Zen Junior]

Hi I'm researching a way to make several servers sparsed apart (about 9 of them) linked using Internet to keep data in sync between them....

Like there will be 8 warehouses located thruout my state were they all must be online and hourly writing their data to a main server... But the main server must also write data to the other 8 server...

Explaining better: I couldn't make all the 8 warehouses use the main server cause internet is not very stable in some areas... Thus If the net is down no one works? Then I thought making 8 server (one for each) would do the trick... Then If someone pays a bill in one of the warehouses it must go to the central server... And if someone pays something on the main server location it must go to the all the other servers...

Is there a way of using replication to help me with this? Or any other automated procedure to make this or should it be done manually designing the tables or something??

I'm kinda of lost cause never done this before and don't even know the name of this....

Thanks for any help...
