Exam 7: Structuring System Process Requirements

A __________ represents data at rest,which may take the form of many different physical representations.

Match each of the following terms with its description. -Breaking a larger system into smaller subsystems or processes.

Assume Process 7.4 produces a data flow and that Process 7.2 must be ready to accept it; we would say that these processes are physically linked to each other.

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

A data flow represents data in motion,moving from one place in the system to another.

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

Referencing a decision table,an action is provided for each rule.

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -The inputs to a process are different from the outputs of that process.

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

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -Objects on a DFD have unique names.

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -A process must have both inputs and outputs.

Assume shipment data is entered into a logbook once shipments are received at the company's warehouse; the logbook is represented on a data flow diagram as a sink.

In a decision table,a condition whose value does not affect which actions are taken for two or more rules is referred to as a(n):

A square on a data flow diagram represents a:

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -A data flow cannot go directly back to the same process it leaves.

Match each of the following terms with its corresponding description. -The part of the decision table that specifies which actions are to be followed for a given set of conditions.

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -A fork in a data flow means that exactly the same data goes from a common location to two or more different processes,data stores,or sources/sinks.

The new logical model will differ from the current logical model by:

Match each of the data flow diagramming symbols with corresponding examples.(Answers may occur more than once.) -A join in a data flow means that exactly the same data comes from any of two or more different processes,data stores,or sources/sinks to a common location.

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