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.

whether they are human nervous

systems, organizational or managerial

information systems, or computer

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.
