Exam 7: Structuring System Process Requirements

On a data flow diagram in the DeMarco and Yourdon model,two parallel lines represent a data store.

Match each of the following terms with its description. -The extent to which information contained on one level of a set of nested data flow diagrams is also included on other levels.

Match each of the following terms with its corresponding description. -Occurs when the condition values are simply "yes" or "no."

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -There must be at least one other process that handles the data flow,produces some other data flow,and returns the original data flow to the beginning process.

Match each of the following terms with its description. -A DFD that is the result of n nested decompositions from a process on a level-0 diagram.

Match each of the following terms with its description. -Graphically representing the functions that capture,manipulate,store,and distribute data between a system and its environment and between components within a system.

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -A process has a noun phrase label.

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -Computing a grade point average

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -Sales report

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.

What is meant by DFD completeness? What is meant by DFD consistency?

If condition one has four values,condition two has five values,condition three has two values,and condition four has three values,then the number of rules required for the decision table is __________.

__________ are the part of a decision table that specifies which actions are to be followed for a given set of conditions.

A __________ is a picture of the movement of data between external entities and the processes and the data stores within a system.

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -A data flow is bi-directional between symbols.

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -Data can move directly from an outside source to a data store.

Identify the deliverables for process modeling.

Data flow diagrams evolve from the more general to the more detailed as current and replacement systems are better understood.

More than one data flow noun phrase can appear on a single arrow as long as all of the flows on the same arrow move together as one package.

A DFD that is a result of three nested decompositions of a series of subprocesses from a process on a level-0 diagram defines a:
