Calling two separate related records

So I have a Person table. There are two types of people, the one who is filling out the report and the person who is the subject of the report. If at all possible, I'd like to be able to pull both of their records from another table using their primary keys. I can't think of how to do this though and may have to resign myself to separating the persons table.

You need to spend a few minutes thinking about the relationship between the REPORTS entity, the PERSONS entity and the PERSON_TYPES (probably best named PERSON_ROLES imho) entity.

Can a report have only two persons (one with type/role subject and one with type/role author)?

This arrangement will result in a different design than if there can be zero or many persons with different types/roles related to one or more reports.

The latter could probably be tackled with a join table for REPORT_PERSONS but the devil is in the details.

See if this helps:

If not, explain how your situation is different.

Nice!
