Modern Systems Analysis and Design,
Chapters 1-6 Study Guide with Correct
Answers

Analysis - Answer✔✔-second phase of the SDLC in which system requirements are studied and

structured. Includes requirements determination and studying the requirements and structure them

according to their interrelationships and eliminate redundancies




The output of this phase = description of the alternative solution recommended


Application software - Answer✔✔-is computer software designed to support specific organizational

functions and processes (inventory management, payroll, market analysis)


an important result of systems analysis and design


CASE tools - Answer✔✔-computer aided software engineering tools - software tools that provide

automated support for some portion of the systems development process


Design - Answer✔✔-the third phase of the SDLC in which the description of the recommended solution

is converted into logical and then physical systems specifications


Implementation - Answer✔✔-the fourth phase in the SDLC in which the information system is coded,

tested, installed, and supported in the organization.

The detailed physical specifications are handed over to programmers. Also includes: initial user support,

finalization of documentation, training programs are finalized


Information Systems Analysis and Design - Answer✔✔-complex organizational process whereby

computer based information systems are developed and maintained


Inheritance - Answer✔✔-the property that occurs when entity types or object classes are arranged in a

hierarchy and each entity type or object class assumes that attributes and methods of its ancestors.

Allows new but related classes to be derived from existing classes


Logical Design - Answer✔✔-the part of the design phase of the SDLC in which all functional features of

the system chosen for development in analysis are described independently of any computer platform


Makes sure the system functions as intended - business aspects of the system


Maintenance - Answer✔✔-the final phase in the SDLC in which an information system is systematically

repaired and improved


Make the changes that users ask for and modify the system to reflect changing business conditions


Object - Answer✔✔-usually correspond to real things an information system deals with. Is a structure

that encapsulates (or packages) attributes and methods that operate on those attributes. Is an

abstraction of a real-word thing in which data and processes are placed together to model the structure

and behavior of the real-world thing


Object class - Answer✔✔-a logical grouping of objects that have the same (or similar) attributes and

behaviors (methods)

OOAD - Answer✔✔-system development methodologies and techniques based on objects rather than

data or processes - often called the third approach to systems development, after the process - oriented

and data - oriented approaches


Physical Design - Answer✔✔-the part of the design phase of the SDLC in which the logical specifications

of the systems from logical design are transformed into technology-specific details from which all

programming and system construction can be accomplished


Planning - Answer✔✔-the first phase in the SDLC in which an organization's total information system

needs are identified, analyzed, prioritized, and arranged.


Rapid Application Development (RAD) - Answer✔✔-systems development methodology created to

radically decrease the time needed to design and implement information systems. Relies on extensive

user involvement, prototyping, integrated CASE tools, and code generators


System developers and end users work together jointly in real time to develop systems


Rational Unified Process (RUP) - Answer✔✔-an object oriented systems development methodology.

Establishes four phases of development: inception, elaboration, construction, and transition. Each phase

is organized into a number of separate iterations


Systems analyst - Answer✔✔-The organizational role most responsible for the analysis and design of

information systems. Primary role - study the problems and needs of an organization in order to

determine how people, methods, and information technology can be best combined to bring

improvements
