I just know two types of Participation: Total and Partial.

Lets take an example of 2 entities Department and Employee.


Relation: For each department there is an Head of the Department (who is an employee again). (Dept-Head-of-emp)
So now for this relation not all the employees are participating in relation Head of.
So
Dept-Head-of will have Total Participation and Head-of-emp will have partial participation.

Note: For Employee works for department relation, you will have total participation on both the sides.
