Exam 7: Structuring System Process Requirements

Having a level-1 diagram with no level-0 diagram is an example of a:

A ________ is a data flow diagram of the scope of an organizational system that shows the system boundaries,external entities that interact with a system,and the major information flows between entities and the system.

The principle of balancing and the goal of keeping a DFD as simple as possible led to four additional,advanced rules for drawing DFDs.

Decision tables support nested conditions.

Student data contained on an enrollment form is represented on a data flow diagram as a:

A gross violation of DFD consistency would be a level-1 diagram with no level-0 diagram.

A condition that has more than two values is a(n):

The part of a decision table that lists the actions that result for a given set of conditions is called:

Briefly discuss modeling logic with decision tables.

A ________ is a DFD that is the result of n nested decomposition of a series of subprocesses from a process on a level-0 diagram.

Completeness,consistency,timing,iterative development,and primitive DFDs are guidelines for drawing DFDs.

A DFD that is the result of n nested decompositions from a process on a level-0 diagram,is called:

Learning the mechanics of drawing ________ is important.

Identify the five basic procedures to follow when constructing a decision table.

Which of the following is a true statement regarding data flows?

A data flow can go directly back to the same process it leaves.

Assume condition one has three values,condition two has four values,and condition three has two values;the number of rules required for the decision table is nine.

Assume the first condition has two values;the second condition has two values;the third condition has three values.How many rules will there be?

The work or actions performed on data so that they are transformed,stored,or distributed defines:

DFD cohesion means your DFDs include all of the necessary components for the system you are modeling.
