Hi, If in my Mendix application I have an object with an attribute and I delete that attribute or that object from the application, what happens? Is the table/column deleted or is it renamed to something else (currentname_deleted)?
Since Mendix 3.0, removed attributes and entities will result in a deleted column/table in your database. There really was no good reason to keep all this old data around and having it fill up the database. We do recommend making a backup of your production database before migrating to a newer version.

Mendix does not delete tables/columns in the database, just renames them.
