Exam 7: Structuring System Process Requirements

A data flow to a data store means update.

Which of the following is not one of the primary deliverables resulting from studying and documenting a system's processes?

Inefficiencies cannot be identified by studying DFDs.

A data flow diagram that represents a system's major processes,data flows,and data stores at a high level of detail refers to:

Data flow diagrams are useful for modeling processes in ________.

The determination of which items are low in stock is represented on a data flow diagram as a process.

Referencing a decision table,specific combinations of conditions trigger specific actions.

For the following situation,draw a context-level diagram and a level-0 data flow diagram.Kellogg State Bank provides car and home loans to its banking customers.Initially,a potential loan customer meets with a Kellogg loan officer,requests a loan for a certain amount and time frame,and completes a loan application.Next,the loan officer determines the customer's credit standing,the type of loan required,and available interest rates.While the loan officer can authorize car loans for credit worthy customers,a loan committee must approve all home loans.

When condition values are either "yes" or "no",these values are called a(n):

If your DFD contains data flows that do not lead anywhere,it is not:

Structured analysis is the process of discovering discrepancies between two or more sets of data flow diagrams or discrepancies within a single DFD.

A ________ is a matrix representation of the logic of a decision,which specifies the possible conditions for the decision and the resulting actions.

In a decision table,an indifferent condition is represented by an asterisk.

On a data flow diagram,a diamond represents a process.

________ are the works or actions performed on data so that they are transformed,stored,or distributed.

Decision tables allow you to represent a set of conditions and the actions that follow from them in a tabular format.

Guidelines for drawing DFDs include the following except for:

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.

Assume we have three conditions.Condition one has two values;condition two has three values;condition three has three values.How many rules are needed?

Referencing a decision table,a limited entry occurs when a condition has only two possible values.
