Exam 9: Process Modeling

_____________________________________ is a language and syntax, based on the relative strengths of structured programming and natural English, for specifying the underlying logic of elementary processes on process models such as data flow diagrams.

A context data flow diagram defines the scope and boundary for the system and project.

In a data flow diagram, rounded rectangles are used to represent _____________________.

A restriction of Structured English is that only ________________________ verbs may be used.

An event is triggered by a discrete output that is completed when the process has responded with the appropriate inputs.

Both decision tables and Structured English can describe a single elementary process.

A hierarchy chart is another name for a decomposition diagram.

The concept of a data attribute is different when drawing data models versus process models.

Process modeling is a technique for organizing and documenting the structure and flow of data through a system's processes and /or the logic, policies and procedures to be implemented by a system's processes.

The domain of an attribute defines what class of data can be stored in that attribute.

The domain of an attribute defines what values an attribute can legitimately take on.

In systems analysis, decomposition allows you to partition a system into logical subsystems of processes for improved communication, analysis and design.

A diverging data flow is one that splits into multiple data flows.

In a data flow diagram, squares are used to represent ________________________.

The packet concept is critical to the creation of data flow diagrams. Data that should travel together should be shown as a single data flow, no matter how many physical documents or attributes are included in the data flow.

A decision table is a tabular form of presentation that specifies a set of conditions and their corresponding actions.

A(n) _____________________________________ is constructed to establish initial project scope.

A process-to-location matrix is a table in which the rows indicate processes (event or elementary processes); the columns indicate locations; and the cells (the intersections of rows and columns) document which processes must be performed at which locations.

The three components of a decision table are: condition stubs, action stubs and rules.

__________________________________ is the act of breaking a system into component subsystems, processes and subprocesses.
