Hi James, Thanks for prompt reply!

Q:Do you need real time replication or periodic?
A:Yes, I need real time replication

Q:Do you need to replicate from head office to Branch A or B…?
A:No, what I need is to replicate DB from branches (A,B,C,D,E) to Head Office.
Q:Do you need to replicate from Branch A to B or C…?
A:Yes, I need is to replicate DB from branches (A,B,C,D,E) to Head Office.

Q:Is it possible that a user at head office will change a row that also will be changed at one of the branches?
A:Yes

Do you need to have any of the data partitioned? For example, some data from A will go to C but not B,D, or E?
A: No.

FYI, I had 4 choices whether I use Sybase ASA 7 (Sorry, I dont have new version) or SQL Server or Oracle 10g Express version or MySQL 5..

Do you have any idea? and can you suggest me what DB system should I use to accomodate the above requirements? ..

Your prompt reply would be appreciated!..

Thanks a lot in advance
