Karma has created custom statues made out of scrap metal for over ten years. He lives above his shop in Long Island, New York. Karma is an accounting fanatic and has kept detailed records of every statue he has ever created. For every sale, he obtains the customer's name and address, a description of the statue, and a picture of the statue sold to the customer. His unique style has recently attracted the attention of several celebrities. Ready to take his business to the next level, Karma has hired you to construct an accounting information system, which he wants modeled after his paper records. As you look over his records, you realize that some customers bought multiple statues at the same time. For example, Gozilla bought a Tin Man Status, a flying horseman statue, and a terrier statue. You realize that in these cases, a single written record will have to be translated into multiple sales records. This is an example of what type of problem in the existing records? a) entity integrity b) insert anomaly c) update anomaly d) referential integrity
