10) Kai Keoni has created custom statues made out of scrap metal for over ten years. He lives
above his shop in Martha's Vineyard, Maryland. Kai 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, Kai 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 sometimes
the same customer is recorded by a slightly different name. For example, Mike Mulligan bought
a horse statue, M. Mulligan bought a pig statue, and Mike M. all seem to be the same person.
This is an example of what type of problem in the existing records?
A) entity integrity
B) referential integrity
C) update anomaly
D) insert anomaly
11) Kai Keoni has created custom statues made out of scrap metal for over ten years. He lives
above his shop in Martha's Vineyard, Maryland. Kai is an accounting fanatic and has kept
detailed records of every statue he has ever created. For every sale, he obtains the customer's

unique style has recently attracted the attention of several celebrities. Ready to take his business
to the next level, Kai 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, Yasmeen Ghuari 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) referential integrity
C) update anomaly
D) insert anomaly

customer last names have different first names in different records. For example, R. Framington
Farnsworth, Bob Farnsworth, and Snake Farnsworth all seem to be the same person. You explain
