Exam 5: Data and Process Modeling

When documenting a process, the documentation includes a description of the process's characteristics and, for functional primitives, a process description, which is a model that documents the processing steps and business logic.

In the Gane and Sarson symbol set, the symbol for a(n) ____________________ is a rectangle with rounded corners.

A gray hole is a process that has ____.

____ is the process of drawing a series of increasingly detailed DFDs, until all functional primitives are identified.

In a DFD, processes contain the business logic, also called business rules, that transform the data and produce the required results.

In modular design, each logical structure must have multiple entry and exit points.

If they pursue the four-model approach, which of the following is a likely outcome?

-A ____ description documents the details of a functional primitive, which represents a specific set of processing steps and business logic.

A DFD shows the structure and detailed contents of a data flow.

-Among the symbols in the accompanying figure, a(n) ____________________ is a path for data to move from one part of the information system to another.

MATCHING Identify the letter of the choice that best matches the phrase or definition.a.balancing f.data dictionary b.structured analysis g.decision table c.leveling h.logical d.DFD i.data flow e.physical j.record -In addition to documenting each data element, all data flows must be documented here.

Two data stores can be connected by a data flow without an intervening process.
