Exam 7: Structuring System Process Requirements

The part of a decision table that lists the conditions relevant to the decision is called:

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

When you believe that you have shown each business form or transaction,computer screen,and report as a single data flow,you have probably reached the:

If a data flow appears on a higher-level DFD but not on lower levels,this situation violates the ________ guideline.

The extent to which all necessary components of a data flow diagram have been included and fully described refers to:

The conservation of inputs and outputs to a data flow diagram process when that process is decomposed to a lower level defines:

The part of a decision table that specifies which actions are to be followed for a given set of conditions refers to:

Make the decision table as simple as possible by removing any rules with impossible actions.

________ are the part of a decision table that lists the actions that result for a given set of conditions.

________ on a DFD have unique names.

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.

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

One of the primary purposes of a DFD is to represent time,giving a good indication of whether data flows occur constantly in real time,once a day,or once a year.

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:

A ________ is the lowest level of decomposition for a data flow diagram.

A decision table does not include:

Assume your local veterinarian records information about each of his patients on patient medical history forms;the collection of medical history forms is represented on a data flow diagram as a data store.

________ is the extent to which all necessary components of a data flow diagram have been included and fully described.

An ________ represents a data flow.

The process in analysis in which the analyst tries to discover discrepancies between two or more sets of data flow diagrams,representing two or more states of an information system,or discrepancies within a single DFD,is referred to as:
