Exam 7: Structuring System Process Requirements

________ are NOT a component of data flow diagram symbols.

No process can have only ________.It would be making data from nothing (a miracle).If an object has only outputs,then it must be a source.

There are two different standard sets of DFD symbols and each set consists of three symbols that represent the same things.

A ________ can be best understood as data in motion,moving from one place in a system to another.

________ are NOT a part of a decision table.

Balancing is the conservation of inputs and outputs to a DFD process when that process is decomposed to a ________ level.

Use cases written at the fish and ________ levels (sometimes called the clam level)are much more detailed and focus on sub-function goals.

The concept of DFD ________ refers to whether you have included in your DFDs all of the components necessary for the system you are modeling.

What is a DFD? Why are DFDs used?

Once the DFDs are complete,we can examine the details of individual DFDs for such problems as redundant data flows,data that are captured but are not used by the system,and data that are updated identically in more than one location.

As seen from the clouds,as if flying in a plane at 35,000 feet,refers to which level according to Cockburn?

A ________ diagram is a DFD that is generated from n nested decompositions from a level-0 diagram.

A(n)________ in business process modeling shows the sequence of action in a process.

A use-case consists of a set of possible sequences of interactions between a system and ________ in a particular environment,possible sequences that are related to a particular goal.

A ________ is a diagram of process logic where the logic is reasonably complicated.

BPMN stands for ________.

No process can have only ________ and if an object has only that,then it must be a sink.

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

A ________ is the origin and/or destination of the data,and these are sometimes referred to as external entities because they are outside the system.

The act of going from a single system to ________ component processes is called (functional)decomposition.
