Existence dependence, strong/weak relationships/entities 11. "Witch.Crafts LLC" (WC) has created a database of (not yet retired) witches. After intensive research WC found out that any witch owns at least one cat. They also found that a witch takes care of and develops such a close relationship with her cat(s), that the cat(s) would ultimately decease, if its witch would die (we are pleased to note that witches live forever). Also note that the database only contains cats that are being owned by witches. Please draw two sets of ERDs: the first set represents a strong relationship between witches and cats, while the second set shows a weak relationship between the two. Remember that you need to carefully craft, and ider , the primary/foreign keys. Also pay attention to the kind of line you use for depicting the relationships. You may leave out, however, any non-key attributes. Strong relationship (2 pts.) witches cats Weak relationship (2 pts.) witches cats -6
