At first, it is a very great tutoril!!

One little exception... replication from mysql (or evem postgres) dosn't work in my case :/ I saw in text, that querry updating RDBMS data is changing also some drs generated fields. The problem is, that in my tables, those columns and tables dosn't exist. I tried different RDBMS, different drs versions, single table example also don't have them. Can You put some specific over drs versions used here?
