I can create Database Entity without primary key?
Question



In the above ppt slide this is shown that An Entity must have an identifier

but while doing practical I can delete the primary key.


This is a lot of confusion related to prepare for Mobile out system exam.

and It consume my time a lot to resolve.



Please give explanation. (Outsystem team) ?


or kindly provide me sample questions or quiz so that I can prepare well.

Like the text says: an entity must have an identifier to allow relationships. No identifier, no relationships.

To be clear: If Customer has no id, it can still reference other entities. But it can't be referenced by others.
