A collection of guidelines that help the analyst complete a system development activity or task is

a technique.

An overall strategic plan to define all of the information systems the organization needs to conduct business is called a(n)

application architecture plan.

The data entities from the entity-relationship diagram correspond to

data stores on the DFDs.

The structured analysis technique evolved in the early 1980s to

help clarify the requirements for the computer system to the developers before they designed the programs.

A data flow diagram (DFD) is best described as showing

inputs, processes, storage, and outputs and how they function together.

IDE stands for

integrated development environments.

When a hierarchy of multiple modules involves multiple programs, such an arrangement is sometimes called

modular programming.

A thing in the computer system that can respond to messages is a(n)

object

A tool is comprised of

software support that helps create models or other components required in the project.

The class diagram shows

the types of objects in a system.

A representation of some important aspect of the real world is a

tool

Software support that helps create models or other components required in the project is a(n)

The process dependency diagram shows

which processes are dependent on other processes/less inputs and outputs than the DFD/which events trigger the processes.
