Exam 5: Data and Process Modeling

Later in the systems design phase, you build a logical model that describes how a system will be constructed. _________________________

MATCHING Identify the letter of the choice that best matches the phrase or definition. -With this, an analyst starts with an overall view, which is a context diagram with a single process symbol.

In modular design, a rectangle represents a condition or decision, a diamond shape represents a step or a process, and the logic follows the lines in the direction indicated by the arrows.

When structured English is used, which of the following rules must be conformed to?

In addition to describing each data element, data flow, data store, record, entity, and process, the data dictionary documents the relationships among these components.

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

____________________ is a subset of standard English that describes logical processes clearly and accurately.

Two DFDs are leveled, for example, if the child diagram at the bottom has the same input and output flows as the parent process at the top of the diagram.

An auto parts store inventory record might include ____.

-In the accompanying figure, the sequence structure is the completion of ____.

In DFDs, a process resembles a(n) ____________________, where the inputs, outputs, and general functions of the process are known, but the underlying details are not shown.

Many valuable reports can be obtained from a data dictionary, including a(n) ____.

The disadvantage of the four-model approach is ____.

When drawing DFDs, a data store is shown only when two or more processes use the data store.

MATCHING Identify the letter of the choice that best matches the phrase or definition. -Model that describes how a system will be constructed.

In a DFD, the Gane and Sarson symbol for a process is a ____.

When a DFD is exploded, the higher-level diagram is called the child diagram, and the lower-level diagram is referred to as the parent diagram.

On what structure(s) is modular design based? Briefly define each of the structure types.

A spontaneous generation process is a process that has ____.

____ also is called looping.
