Welcome to ORM!
Yes - I understand that the terminology can be confusing so I hope that the following explanation helps.
Objects: ORM uses the concept of an "Object Type" which is not the same as an object in OO.
An ORM Object Type can be either an "entity type" or a "value type".
The "date" data type: If you are using NORMA, then you will find a data type called "CE". This stands for "Christian Era".
The following example uses the object type "Date(.CE)"
As you can see, there is only one ORM "date" object but the relational mapper has mapped the single "date domain" to two completely different concepts in two different tables (viz. date of birth and company formation date).
