This document discusses several types of information systems used in business. It describes transaction processing systems as systems that handle business transactions by collecting, modifying, and retrieving transaction data. It also outlines office automation systems, which use computer hardware and software to digitally manage office tasks. Additionally, the document discusses knowledge work systems that help capture and share organizational knowledge, as well as decision support systems and executive support systems that aid various levels of management in decision making. Finally, it summarizes group decision support systems that are designed to facilitate meetings and group work through collaboration technology.

3. TRANSACTION
PROCESSING
SYSTEM
It is an information
processing system for
business transactions
involving business
transactions involving
the collection,
modification , and
retrieval of all
transaction data. It is
also known as
transaction processing
or real-time
processing.

4. Where it is being used?
Businesses such as IT merchant services or other
parts of the software architecture.
It is a model for various transactions, including both
financial transactions and other processes like
verifications.
It provides data for other business processes like
management information system/ decision support
system and special purpose information systems.
It can also be used to capture and process data that
describes fundamental business transactions, update
databases and to produce a variety of reports.

5. Examples of systems that fall into
Transaction Processing System
IBM Transaction Processing Facility ( TPF)
IBM Information Management System (IMS)
IBM Customer Information Control System ( CICS)
UNIVAC Transaction Interface Package (TIP)

6. Office Automation
System (OAS)
Office Automation System
refers to the varied
computer machinery and
software used to digitally
create, collect, store,
manipulate, and relay
office information needed
to accomplishing basic
tasks. Raw data storage,
electronic transfer, and the
management of electronic
business information
comprise the basic
activities of an OAS. It
also helps in optimizing or
automating existing office
procedures.

7. Where does OAS being used?
The conversion of information to electronic form
The backbone is a LAN, which connects users to
transmit data, mail, and even voice across the
network.
Its advantages are the following:
Office automation can get many tasks accomplished
faster.
It eliminates the need for a large stuff.
Less storage is required to store data.
Multiple people can update data simultaneously in
the event of changes in schedule.

8. Systems that fall into OAS
Document Management Systems
Message Handling Systems
Teleconferencing Systems

9. Knowledge Work
Systems( KWS)
KWS serves the
information needs at
the knowledge level of
the organization. It is
the process of
capturing, developing,
sharing, and effectively
using organizational
knowledge. It refers to
a multi-disciplined
approach to achieving
organizational
objectives by making
the best use of
knowledge.

10. Where it is being used?
It can be used by people who hold formal university
degrees and who are often members of a recognized
profession such as lawyers, engineers, doctors, and
science. Their job consists primarily of creating new
information and knowledge.
KWS, such as scientific or engineering design
workstations, promote the creation of new knowledge
and technical expertise are properly integrated into
the business.

11. Examples of systems that fall into
KWS
Computer - aided Design (CAD)
Computer aided Manufacturing (CAM) Virtual reality
systems
Virtual Reality Modelling Language (VRML)
Investment workstations
Computer Design System

12. Decision Support
System (DSS)
A Decision Support
System (DSS) is a
computer based
information system
that supports
business or
organizational
decision-making
activities. It can
either be
computerized,
human, or a
combination of both.

13. Where it is being used?
DSS serves the management, operations, and
planning levels of an organization and help to make
decisions, which may be rapidly changing and not
easily specified in advance.
DSS applications are not single information
resources, such as a database or a program that
graphically represents sales figures, but the
combination of integrated resources working
together.

14. Examples of systems that fall
under DSS
File Drawer systems
Suggestion systems
Optimization systems
Representational models
Accounting models
Analysis information systems
Data Analysis Systems
University of Vermont PROMIS system (for medical
decision making)

15. Executive Support
System (ESS)
An Executive Support
System (ESS) is a software
that allows users to
transform enterprise data
into quickly accessible and
executive- level reports,
such as those used by
billing , accounting, and
staffing departments . It is
also known as Executive
Information System ( EIS).
It is commonly considered
a specialized form of
decision support systems.

16. Where it is being used?
It enhances decision making for executives.
Used by billing, accounting, and staffing
departments.
It facilitates and supports senior executive
information and decision-making needs.
It provides easy access to internal and external
information relevant to organizational goals.

17. Examples of systems that fall
under ESS
Corporate Management
Technical Information Dissemination
Cambridge Systematic

18. Group Decision
Support Systems
(GDSS)
Group-Decision
Support Systems
(GDSS) are a class of
electronic meeting
systems, a
collaboration
technology designed
to support meetings
and group works. It
is also categorized
within a time-place
paradigm.

19. Where is GDSS being used?
It is designed to support meetings and group works.
It is more focused on task support.
It has come to mean computer software and
hardware used to support group functions and
processes.
“High –level managers can spend 80% of their time
making decisions on groups, thus, GDSS can reduce
this time, arriving at a better decision faster.”
It provides the hardware, software, databases, and
procedures for effective decision making.

20. Types of GDSS
Suggestion model
File Drawer system
Group Decision Room
