Object-Oriented Analysis (OOA)

Front 15

An approach to system development that views an information system as a collection of interacting objects that work together to accomplish tasks

Back 15

Object-Oriented Approach

Front 16

Defining all the types of objects necessary to communicate with people and devices in the system, showing how objects interact to complete tasks, and refining the definition of each type of object so it can be implemented with a specific language or environment

Object-Oriented Programming (OOP)

Front 18

Related system development activities, which are grouped into categories of project planning, analysis, design, implementation, and support

Back 18

Phase

Front 19

Back 19

Planning Phase

Front 20

The area of the user’s business for which a system is being developed

Back 20

Problem Domain

Front 21

A planned undertaking that has a beginning and an end, and that produces a desired result or product

Back 21

Project

Front 22

A database that stores information about the system in a CASE tool, including models, descriptions, and references that link various models together

Back 22

Repository

Front 23

A graphical model showing the hierarchy of program modules produced by the structured design technique

Back 24

Structure Chart

Front 25

A technique that helps the developer define what the system needs to do (the processing requirements), what data the system needs to store and use (data requirements), what inputs and outputs are needed, and how the functions work together as a whole to accomplish tasks

Back 25

Structured Analysis

Front 26

System development using structured analysis, structured design, and structured programming techniques

Back 26

Structured Approach

Front 27

A technique providing guidelines for deciding what the set of programs in an IS should be, what each program should accomplish, and how the programs should be organized into a hierarchy

Back 27

Structured Design

Front 28

A program or program module that has one beginning and one ending, and for which each step in the program execution consists of sequence, decision, or repetition constructs

Back 28

Structured Program

Front 29

The phase of the SDLC whose objective is to keep the system running productively after it is installed

Support Phase

Front 30

Comprehensive guidelines to follow for completing every activity in the systems development life cycle, including specific models, tools and techniques

Unified Process (UP)

Front 36

An approach to executing an SDLC (in which one phase leads (falls) sequentially into the next phase

Back 36

Waterfall Approach

Front 37

What are the five phases of the Systems Development Life Cycle (SDLC)?

Back 37

Planning, Analysis, Design, Implementation & Support

Front 38

What is iteration across phases?

Back 38

Iteration means that work activities are done once, then again and yet again. With each iteration the result is refined so that it is closer to what is needed.

Front 39

What is incremental development?

Back 39

With this approach, you complete parts of the system in one or more iterations and they you put the system into operation for the users.

Front 40

What is System Development methodology?

Back 40

A methodology that provides guidelines to follow for completing every activity in the systems development life cycle, including specific models, tools and techniques.

Front 41

What are the two main approaches to systems analysis and design?

Back 41

Traditional approach and object-oriented approach
