Database 1 is a replica (1 way) to Database 2 I go in and make changes (attribute updates) to Database 1. Save the edits and synchronize the databases. I load in the data from Database 2 to make sure that the changes are there. And they are present.
Now I switch over to SQL Server Mgmt Studio and query Database 1 OR Database 2 and the updates are not present.
And while you're on it, you may as well consider reading some of the links regarding versioning and data management in a ESRI Geodatabase that I pointed out in this post in another thread, so as to really start understanding it.
Especially the 2004 ESRI Versioning Whitepaper linked there is highly recommended reading, despite it's age.
