need algorithm to synchronize 2 db's

[sandro77]

i'm writing a program in java that, working with Jdbc-Odbc driver, writes and reads to/from two Ms Access databases.
these db's, in the beginning match exactely (same content+same structure), but can be modified separately by different users (changes in the first db are'nt the same that in the second). i'm looking for an algorithm (that i think is called "update propagation algorithm", and i know is already been written) that will change the first db with the modifies in the second and viceversa, in order to have, at last, two db's that match exactely.

doesn't matter in which language this algorithm is written, i need what it does.
thanks for the attention

Sandro77,

I don't think there is a person on this site that is going to sit down and spend several hours writing this code for you. We might help you write it, but not do it for you. Even if all we do is help, we will need more information, the descriptions of these database's, etc...

As a pointer to you, have you looked into replication? Terry M. Hoey

thanks for your answer, really i did'nt want someone writing this algorithm for me, i only needed some indication about where to find it (because it already exist!)
your tip was very helpfull
thanks a lot
