Changes in the table when assigning class as Principal Class

[apbalaban]

Hi community members!

I needed to add a bunch of classes as Principal Class (I was doing it in CI Class Manager), and sometimes along with updates to cmdb_class_info table there were changes to actual tables: 

Not every table got updated, and I don't understand where and how it happened in the first place, cause I was using only CI Class Manager. I compared previous and current versions of the tables and there were no differences found. 

Can anyone explain what got updated and where?

Thanks!
