Question 1

(TCO 5) Which of the following is a true statement?

• Data characteristics are dynamic.

• A data model explains the transient form of an organization.

• An information system design based on a data orientation, rather than a process or logic orientation, should have a longer, useful life.

• Data flow paths are permanent.

• A data model graphically represents the processes that capture, manipulate, store, and distribute data between a system and its environment and among components within a system.

Question 2

(TCO 5) A person, place, object, event, or concept in the user environment about which the organization wishes to maintain data refers to a(n)

• attribute.

• data element.

• relationship.

• entity.

• process.

Question 3

(TCO 5) Vehicle identification number, color, weight, and horsepower best exemplify

• entities.

• entity types.

• data markers.

• identifiers.

• attributes.

Question 4

(TCO 5) An attribute that can have more than one value for each entity instance is referred to as

• gerund.

• a multivalued attribute.

• a nonexclusive attribute.

• a data replica.

• None of the above

Question 5

(TCO 5) If student and course participate in a relationship, this is an example of a(n)

• unary relationship.

• coupled relationship.

• binary relationship.

• ternary relationship.

• extraordinary relationship.

Question 6

(TCO 5) A relationship between instances of two entity types is a

• unary relationship.

• binary relationship.

• ternary relationship.

• multiple occurrence.

• partnership occurrence.

Question 7

(TCO 5) The minimum number of instances of entity B that may be associated with each instance of entity A defines the

• degree of the relationship.

• minimum cardinality of the relationship.

• maximum cardinality of the relationship.

• domain of the relationship.

• join level.

Question 8

(TCO 6) Selecting the best alternative system involves

• generating a comprehensive set of alternative design strategies.

• selecting the alternative design strategy that is most likely to result in the desired information system, given all of the organizational, economic, and technical constraints that limit what can be done.

• developing all technology and organizational specifications necessary to implement the new information system.

• working with a customer to establish work standards and communication procedures.

• generating a comprehensive set of alternative design strategies and selecting the alternative design strategy that is most likely to result in the desired information system, given all of the organizational, economic, and technical constraints that limit what can be done.

Question 9

(TCO 6) Which of the following is a true statement regarding midrange alternatives?

• Midrange alternative design strategies often do not involve computer technology; instead they focus on making paper flows more efficient or reducing redundancies in current processes.

• Midrange alternative design strategies represent compromise solutions.

• Functionality is the primary focus of midrange alternative design strategies.

• Midrange alternative design strategies provide all the required functionality users demand with a system that is minimally different from the current system.

• Midrange alternative design strategies provide all the desired features using advanced technologies that often allow the system to expand to meet future requirements.

Question 10

(TCO 6) The most conservative solutions in terms of the effort, cost, and technology involved in developing a new system are the

• low-end solutions.

• high-end solutions.

• midrange solutions.

• constraint-dependent solutions.

• requirements-dependent solutions.
