WGU C798 Informatics Systems Analysis & Design II Questions and answersMethodologies ✔High level approach to something; does not tell you HOW to do things
Techniques ✔How to do what you need, part of the methodology
Tools ✔What you use to execute your techniques
Application Software ✔Computer Software designed to support organizational functions or processes. Ex: excel
Systems Analyst ✔Organizational role most responsible for analysis and design of information systems. Ex: your browser
System Development Methodology ✔A standard process followed in an organization to conduct all the steps necessary to analyze, design, implement, and maintain information systems
Systems Development Life Cycle (SDLC) ✔Traditional methodology used to develop, maintain, and replace information systems. Phases are: Planning, Analysis, Design, Implementation, Maintenance
I-P-O Model ✔Input-Process-Output Model: The input is being converted into an output; naturally occurring, there are no closed systems
System ✔Group of components working together towards a common goal
Model ✔A representation of something; a form of communication; it is NOT relevant - it's an
abstraction/simplification. The purpose is to communicate & understand.
Planning ✔An organization's total IS needs are identified, analyzed, prioritized, & arranged
Analysis ✔System requirements are studied and structured
Design ✔A description of the recommended solution is converted into logical and then physical system specifications
Logical Design ✔All functional features of the system chosen for development in analysis are described independently of any computer platform
Physical Design ✔The logical specifications of the system from logical design are transformed into the technology-specific details from which all programming and system construction can be accomplished
Implementation ✔The information system is coded, tested, installed, and supported in the organization
Maintenance ✔An information system is systematically repaired and improved
Computer-Aided Software Engineering (CASE) Tools ✔Diagramming tools enable graphical representation; computer displays and report generators help prototype how systems "look and feel"; IBM's Rational products are the best known CASE tools; Analysis tools automatically check for consistency in diagrams, forms, and reports; A central repository provides integrated storage of diagrams, reports, and project management specifications; Documentation generators standardize technical and user documentation; Code generators enable automatic generation of programs and database code directly from design documents, diagrams, forms, and reports
