Data Flow Diagram (DFD) - correct answer ✔A picture of the movement of
data between external entities and the processes and data stores withing a
system.


Data store - correct answer ✔Data at rest, which may take the form of many
different physical representations


Process - correct answer ✔The work or actions performed on data so that
they are transformed, stored or distributed.


Source/Sink - correct answer ✔The origin and/or destination of data;
sometimes referred to as external entitites.


Context diagram - correct answer ✔An overview of an organizational system
that shows the system boundaries, external entities that interact with the
system, and the major information flows between the entities and the system.


Level-0 diagram - correct answer ✔A DFD that represents a system's major
processes, data flows, and data stores at a high level of detail.


Functional Decomposition - correct answer ✔An iterative process of breaking
the description of a system down into finer and finer detail, which creates a set
of charts in which one process on a given chart is explained in greater detail
on another chart.


Level-n diagram - correct answer ✔A DFD that is the result of n nested
decompositions from a process on a level-0 diagram.

, Balancing - correct answer ✔The conservation of inputs and outputs to a
DFD process when that process is decomposed to a lower level.


DFD completeness - correct answer ✔The extent to which all necessary
components of a DFD have been included and fully described.


DFD consistency - correct answer ✔The extent to which information
contained on one level of a set of nested DFDs is also included on other
levels.


Timing - correct answer ✔DFDs do not do a good job of representing time.
There is no indication of when a system would run.
Draw DFDs as if the system you are modeling has never started and will
never run.


Iterative Development - correct answer ✔an approach to system
development in which the system is "grown" piece by piece through multiple
iterations.
With each attempt, you will come closer to a good approximation of the
system or aspect of the system you are modeling.


Primitive DFD - correct answer ✔The lowest level of decomposition for a
DFD.


Decision table - correct answer ✔A matrix representation of the logic of a
decision; it specifies the possible conditions for the decision and the resulting
actions.

between two or more sets of DFD or discrepancies within a single DFD.
