Hello
I am new in the field of Database Management. Most of times i worked with
Software development and Database Design.
I need some advice regarding database management.
I have three Database (DB) servers at different locations. suppose A, B and
C as three servers. where as Z is a central server which have VPN to all
other servers.
I have to insert/update records to central server Z if there is any
insert/update in any of the A,B and C server.
Now I can write a JAVA code that when ever there is insertion/updation of
record of A/B/C do same in central Server Z using JAVA sockets I can send
records to central server where Socket server will listen and then insert or
update records in DB.
But I come to know that there is a concept called Replication.
I studied it and found that it is used for load balancing. I dont need load
balancing I only need to Syncronize only Two tables of all A,B,C servers to
central server Z.
Please suggest how to move forward.(Open source solutions )
