TEST BANK System analysis and design chapter 1-4 ( PART 1)
STUDY GUIDE FOR MID TERM AND SUMMER EXAMS
Information system A set of interrelated components that collects processes stores and
provides as output the information needed to complete business task . Always includes people
who operate the system and carry out some of the work
Systems analysis Those system development activities that enable a person to understand
and specify what the new system should accomplish
Systems design System development activities that enable a person to describe in detail
how the resulting information system will actually be implemented
Project A planned undertaking that has a beginning,end, and produces end results
SDLC System development life cycle
System development life cycle A framework that identifies all the activities required to
research, build, deploy, and often maintain an information system
System development process Or system development methodology, a set of comprehensive
guidelines for carrying out all the activities of each core processor of the SDLC
Name the SDLC core processes 1. Identify the problem and obtain approval
2. Plan and monitor the project
3. Discover and understand the details of problem or need
4. Design system components
5. Build, test,and integrate system components
6. Complete system tests and deploy the solution
Agile Development An information system development process that emphasizes flexibility
and rapid response to anticipate new and changing requirements during development
Iterative developmentAn approach to system development in which the system is "grown" piece
by piece through multiple mini projects called iterations
Subsystem An identifiable and fully functional part of a complete system
, The planning process for an iteration consists of three steps: -Identify the tasks required
for the iteration
-Organize and sequence these tasks into a schedule
-Identify required resources (especially people) and assign people to tasks
WBS Work breakdown structure
What is the WBS After tasks of an iteration are identified, they are compiled and organized
into a document by order of importance, this includes estimates of how long each task will take.
Iteration schedule Tasks taken from the WBS and placed them on day-by-day sequence.
Two core process 1 activities (called pre-project activities) -Identify the problem and document
the objective of the solution system
-Obtain approval to commence the project
System Vision Document Document that shows the problem description, system
capabilities, and business benefits.
Three core process 2 activities -Determine the major components (functional areas) that
are needed
-Define the iterations and assign each functional area to an iteration
-Determine team members and responsibilities
Core process 3 activities: -Do fact-finding tasks to understand the requirements
-Develop a list of use cases and a use case diagram
-Develop a list of classes and a class diagram, define user experience with sketches of screens
and reports needed for each use case
Use case a document showing a case or situation where the system is used.
ex/USE CASE: Look up supplier, DESCRIPTION: using suppler name, find supplier information and
contacts
Domain classes Identifies the things in the real world that the system needs to know
about and keep track of. To find domain classes, we look for all objects or things that a system
uses or captures.
EX/Object class: Supplier Attributes: Supplier name, address, description, comments
