Structure of MIS::Structure of MIS is a difficult concept to understand because there is no standard or universally accepted framework for describing management information system.

Physical components ,

Information system processing functions,

Decision support 

Levels of management activities

Organizational functions

MIS Structure Based on Physical components:Structure of MIS may be understood by looking

at the physical components of the information system in an organization.

Hardware : Hardware refers the physical data processing equipment and peripheral devices.

Software: software is broad term given to the instruction or program that direct the operation of the hardware.

Database: the data base consist of all data utilized by application software.

Input and output:  various physical input and output from the

information system, existing in output from the information system, existing in the form like printout, report etc.

Information system processing functionsInformation system structure can also be

understood in term of its processing functions. The main processing functions of information system are described below:

To process transactions: Information systems process transaction may be defined as an activity taking place in an organization

To Maintain Master files: Information systems create and maintain master files in the organization. A master file stores the historical data about the organizational

To Produce ReportsReports are significant products of an

information system. Many reports are produces on a regular basis, which are called scheduled reports.

Decision SupportDecision vary with respect to the structure that can be provided for making them. A highly structured decision can be pre-planned. A structured decision, because of its well defined nature can be said to be programmable.

Level of management activitiesThe structure of an information system can be categorized in terms of level of the management activities

Management control level includes acquisition and organization of resource, structuring of work and training of personnel

Operational control is related to short-term decision for current operations. Pricing, ,inventory level etc

Organizational functionsThe structure of MIS can also be described

in terms of organizational functions which make use of information.

The term organizational function information systems is used to describe a variety of information system that support an organizational function such as accounting, finance, production, marketing, human resource management etc. Each of these functions has its own information needs.

MIS is a typically an integrated combination of functional information systems that is designed to meet the info requirements of the functional subdivisions of an organization.

Each of these functions is considered as a subsystem. These subsystems have info application related to that function only.
