    Simple R.D. question

    Hi there,

    A simple question I need confirming if anyone can help.

    A farm is required to take details of the female sheep and of the male sheep with which they have mated. A male may be mated with many females and a female may mate with many males.

    The question is; what are the names of the super and sub entities?

    From my knowledge the male sheep is a sub and so is the female sheep.

    What i need to know is if there are any super entities?

    Thanks

    If Male Sheep and Female Sheep are sub-entities, then Sheep is a super-entity.
