Exam 7: Structuring System Process Requirements

A matrix representation of the logic of a decision,which specifies the possible conditions for the decision and the resulting actions,defines a:

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

In the Gane and Sarson model,a rectangle with rounded corners on a data flow diagram represents a:

If Rules 2,4,and 6 are indifferent conditions,then:

A data flow repository entry would include the composition or list of data elements contained in the data flow.

Recording a customer's payment is represented on a data flow diagram as a:

Functional decomposition is an iterative process of breaking the description of a system down into finer and finer detail.

Match each of the following terms with its description. -Data in motion,moving from one place in a system to another.

Briefly discuss modeling logic with decision tables.

Data flow diagrams that concentrate on the movement of data between processes are referred to as:

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

Referencing a decision table,every possible combination of conditions must be represented.

On a data flow diagram,supplier information kept in a notebook is represented as a __________.

If a data flow appears on the context diagram and is also represented at level-0,this would be referred to as:

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

Removing any rules with impossible actions to make which of the following simple as possible?

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.

In the DeMarco and Yourdon model,the symbol for a data store is __________.

Data cannot move directly from a source to a sink.

__________ are the part of a decision table that lists the conditions relevant to the decision.
