Hi, With respect
According to this diagram:



And the following information:
- 200 records in the Employee entity
- 5 records in Project entity

In your opinion,
What is the minimum and maximum number of records to Natural join these two entities? Minimum = 200 and Maximum = 1000 ? or Minimum = 0 and Maximum = 1000 ? and Why?

Thank you very much
