INFORMATION PROCESSING
COMPONENTSThe Architecture of components
of computers and their information
interaction is a mirror of thefunctioning of the human
physiological information system
(Nervous System)

Likewise the
Architecture ofcomputer systems is
basically similar
to the structure
of information as
organizationscommonly handle it
in business.

INPUT They receive Data, they find things out.
STORE They remember or write Data down forreference.
PROCESS They compare, think about ormanipulate Data.
TRANSMIT They convey or send Data to others.
OUTPUT They record and publish Data in writtenform.

MANAGEMENT INFORMATION
SYSTEMS (MIS) SU
PPORTMANAGERIAL FUNCTIONS
Because information is power, managers
have always managed information by some
method.

In the past, each operational
department (finance, marketing,
production, and its personnel) maintainedseparate information systems to satisfy its
particular needs.

The need for a comprehensive
information system became evident. Theresult was the evolution of the concept of
MANAGEMENT INFORMATION SYSTEM.

MIS can be defined generally as anintegrated, structured complex of people,
machines, and procedures for supplying
relevant data (information) from both external
and internal sources to aid managers in
planning, staffing, communicating, controlling,
and decision-making.

The heart of the integration of information
needed in MSI is a Data Base.
DATA BASE an organized repository of
the organizations information resources
(internal and possibly containing some
external data), including raw data and
procedures

The idea is that the data base consist of
most of the data available in the
organization and can be accessed by
different managers for their varied uses.
One manager may access data for
planning, another for controlling, and all
managers may access data for decision-
making.

One powerful, and probably more easily
used, concept is that of DECISION
SUPPORT SYSTEM(DSS). Although DSS can
be viewed as an application within MIS for
supporting decisions, it has become more
powerful and useful to managers because
of the following developments:

Interactive Computing a dialogue
between the manager and the systemthrough question and response.
User friendly data base languages andhardware.
Distributed data processing - where atleast some portion of the computingfunction is decentralized via remoteterminals.

The managers office of the future hasbeen predicted to be built around
executive terminals, or work-stations.
These managerial work stations are
multifunction, on-line terminals connected
to a company wide information network.
