Who controls ZZZ_ObjectStructure ? AstoreBase.mdf ? or some dll files?

Dear Experts,

Who controls ZZZ_ObjectStructure ? AstoreBase.mdf ? or some dll files (ASDataObjects.dll , or ASRepository.dll )?

What are the uses of these ZZZ things ?

[Sebastian_Eiche]

As I know all ZZZ_ entries are "old" and the development rename them to "zzz" so that they're always at the end of Tables.
The objectstructue table is placed in the Astorbase. As you will see it's a combination of the tables "ObjectType" and "ObjectSubtype".

Dear @Sebastian_Eiche 

I believe the same logic

but doubt started when some exception was thrown from the AstorDataObjects.dll and some othertime from the AstorRepository.dll

I used to think these are only from the astorbase.mdf

but now i think these are hardcoded names in the dll files also
