May I ask what resources you are using in your OSPF studies so we can try to give you some point of reference? You may need a different resource, because the DR and BDR election is not all that complicated.

May I ask if you have a CCNA?

Someone in the CCNA Forum who's studying this for the CCNA may have a better link, since this is a CCNA topic, but try this one.

In the above diagram, all routers share a common multi-access segment.

the DR represent the segment to prevent excess messaging and un-necessary adjacencies and is always present in multi-access segment whether it is ethernet or frame relay. Works the same way as DIS on IS-IS
