Why each option
When extending a table, the extended table inherits all fields from its base table, so only new, specific fields need to be created.
Reference fields for the base table are already part of the base table and are automatically inherited by the extended table, so they do not need to be recreated.
The fields that are not in the base table are precisely the ones you need to create, as an extended table automatically inherits all fields from its parent table.
Mandatory fields for the base table are also inherited by the extended table; they do not need to be explicitly created again.
Fields that are specific to the extended table are the unique attributes or data points required for the specialized records in the extended table that do not exist in the general base table.
