Seminar on Management Information System

Information System & its components

An information system can be defined technically as a set of interrelated components that collect (or retrieve), process, store, and distribute information to support decision making and control in an organization.

In addition to supporting decision making, coordination, and control, information systems may also help managers and workers analyze problems, visualize complex subjects, and create new products.

Functions of MIS :-

Components Of MIS :-

1. Resources of people: (end users and IS specialists, system analyst, programmers, data administrators etc.).

2. Hardware: (Physical computer equipments and associate device, machines and media).

3. Software: (programs and procedures). 4. Data: (data and knowledge bases)

5. Networks: (communications media and network support).

1.Resources of people

End users: (also called users or clients) are people who use an information system or the information it produces. They can be accountants, salespersons, engineers, clerks, customers, or managers.

IS Specialists: people who actually develop and operate information systems. They include systems analysts, programmers, testers, computer operators, and other managerial, technical, and clerical IS personnel.

2. Hardware Resources

Machines: as computers and other equipment along with all data media, objects on which data is recorded and saved.

Computer systems: consist of variety of interconnected peripheral devices. Examples are microcomputer systems, midrange computer systems, and large computer systems.

3. Software Resources

Software Resources includes:

System software, such as an operating system

Application software, which are programs that

direct processing for a particular use of computers

by end users.
