If you allow managers to have manager access, they will be able to delete database.  If they are deleting the file using the adminP, then ou may be able to stop them by not allowing them to hav access o the Admin4.nsf.  Wenever the Admin Process tries to delete a database, it will require Administrator Approval in the Admin4.nsf.

If accidental deletions happen, they happen because people right-click a database icon, then select Application -> Delete -> [Yes] (without reading the message). Not via the AdminP, unfortunately.

Yes, probably the only way will be lowering newbies from Manager to Designer, although that means that they cannot do simple things like assigning a user an ACL role or adding somebody to a database ACL. Sadly :(

If a person does not know what they are doing then don't let them have the access rights. If the person needs Manager rights then they better have the training. I have seen way to many N/D applications where people are given Manager rights because that is the easiest way to make sure they can do whatever they need, but the problem is that they can do a lot of really dangerous things they do not need to have. Like delete Documents and delete the database. Proper Applicatin Design and setup is essential.
