How does a system analyst design a new system?
How does a system analyst design a new system?
The correct option is A By identifying subsystems and interfaces between subsystems
By identifying subsystems
and interfaces between subsystems does a system analyst design a new system.
System design is the
process of planning a new business system or one to replace or complement an
existing system. ... System analysis, then, is the process of gathering and
interpreting facts, diagnosing problems, and using the information to recommend
improvements to the system.
Subsystems differ from
packages in their semantics: a subsystem is a kind of package which provides
behavior through one or more interfaces which it realizes. ... Subsystems also
provide a 'replaceable design' element: any two subsystems (or classes, for that
matter) which realize the same interfaces are interchangeable.
A unit or device that is
part of a larger system. For example, a disk subsystem is a part of a computer
system. A bus is a part of the computer. A subsystem usually refers to
hardware, but it may be used to describe software.
The interrupt is the only
way users can interact with a computer system. When users run an application,
the application obtains services from the operating system by making system
calls. The operating system normally implements a generic routine to handle all
system calls.
