This Slide continue the 2nd session of MIS Unit no 3 syllabus which discussed about the TPS,OAS,DSS,ESS,ISs

1. Unit 3: Introduction to
Information Systems and MIS

2. First Answer this questions:
• What is Data ?
• What is information and its
attributes ?
• What is MIS ?

3. Agenda
TPS,
OAS,
DSS,
ESS,
ISS

4. ISs (Information Systems)

5. But first what is :
System and
Subsystem ?

6. System and Subsystem
Report
Generator
Account
Department
HR
Department
Marketing
Department
Production
Department

7. Definition
• System : A system is an array of component
that work together to achieve a common goal
(or multiple ).
• Subsystem : A system consist of several
subsystem- component of larger system-with
sub goals , all contributing to meeting the main
goal.

8. Now what is Information System ?
• It consist of all the component that work
together to process data and produce
information.
• It consist of many systems with sub goals , all
contributing to the organization’s main goal

9. Four Stages of Processing in IS

10. Component of Information System :
• Data
• Hardware
• Software
• Telecommunication
• People

11. Data
 It is a input the system takes
produce information.

12. Hardware
• A computer and its peripheral
equipment : input , output and storage
devices

13. Software
• Sets of instructions that tell the
computer
How to :
• take data in
• process it
• display information
• store data and information

14. Telecommunication
• Hardware and software that facilitate fast
transmission and reception of text , picture ,
sound and animation in the form of electronic
data.

15. People
• Information system professionals and
users.

16. Lets look at
TYPES of
Information
System/MIS

17. Overview
, OAS

18. TPS ( Transactional Processing System)
• Transaction processing is a style of computing that
divides work into individual, indivisible operations, called
transactions.
• A transaction processing system (TPS) is a software
system, or software/hardware combination, that
supports transaction processing .
• Ex. Purchasing Tickets , Withdrawing money cancel
appointment.

19. Types of TPS
• Online transaction processing
• Batch transaction processing

20. Online Transaction Processing(OLTP)
• It involves a direct connection between the
operator and the TPS program.
• It provide immediate results
• It used to process a single transaction at a time
• Ex:

21. Batch Processing System
• In this type transaction are grouped
together and processed as unit
• Ex: Cheque processing system in bank

22. Features of TPS
• Performance
• Continuous availability
• Data integrity
• Ease of use
• Modular growth

23. Performance
• Fast performance with a rapid
response time is critical.

24. Continues Availability
• The system must be available during the
time period when the users are entering
transactions.

25. Data Integrity
• Multiple users must be protected from
attempting to change the same piece of data at
the same time.
• Ex: two operators cannot sell the same seat on
an airplane

26. Ease of use
• The system should be simple for them to
understand.

27. Modular growth
• It should be possible to add, replace, or update
hardware and software components without
shutting down the system.

28. OAS (Office automation System)
• Information system developed to make office more
efficient called the office automation system (OAS).
• A variety of office automation systems are now applied
to business and communication functions. Saving both
time and money.

29. Types of functions
• Electronic publishing
• Electronic communication
• Image processing
• Office management.

30. Electronic Publishing
• Electronic publishing systems include
word processing and desktop publishing.

31. Electronic Communication
• Electronic communication systems
include electronic mail (), voice mail,
facsimile (fax), and desktop video
conferencing
e-mail
voice mail
fax

32. Image Processing
• Imaging systems convert text, drawings,
and photographs into digital form that
can be stored in a computer system.

33. Office Management
• These systems provide an electronic means of
organizing people, projects, and data.

34. Time for 5 min Break

35. Before going further
tell your decisions about :
Daily Weekly
Yearly Lifetime

36. DSS (Decision Support System)
• Decision support systems (DSS) are interactive
software-based systems intended to help
managers in decision-making.
• A decision support system helps in decision-
making but does not necessarily give a decision
itself.

37. Types of DSS
• Status Inquiry System
• Data Analysis System
• Information Analysis System
• Accounting System

38. Status Inquiry System
• It helps in taking operational,
management level, or middle level
management decisions
• For example daily schedules of jobs to
machines or machines to operators.

39. Data Analysis System
• It needs comparative analysis and makes
use of formula or an algorithm
• For example cash flow analysis,
inventory analysis etc.

40. Information Analysis System
• In this system data is analyzed and the
information report is generated.
• For example, sales analysis, accounts
receivable systems, market analysis etc.

41. Accounting System
• It keeps track of accounting and finance
related information.
• For example, final account, accounts
receivables, accounts payables.

42. Attributes of a DSS
• Adaptability and flexibility
• High level of Interactivity
• Efficiency and effectiveness
• Complete control by decision-makers
• Standalone, integrated, and Web-based

43. ESS/EIS (Executive Support System)
• These information are often external,
unstructured and even uncertain.
• This information is intelligence based:
– Market intelligence
– Investment intelligence
– Technology intelligence

44. Characteristics of the ESS
• Informational characteristics
• User interface/orientation
characteristics
• Managerial / executive characteristics

45. Informational characteristics
• Flexibility and ease of use.
• Provides the timely information with the
short response time and also with the
quick retrieval.
• Produces the correct information.
• Produces the relevant information.
• Produces the validated information.

46. User interface/orientation characteristics
• Contains the user friendly interfaces
• consisting of the graphic user.
• Can be used from many places.
• Offers secure reliable, confidential access along with the
access procedure.
• Is very much customized.
• Suites the management style of the individual
executives.

47. Managerial / executive characteristics
• Supports the over all vision, mission and the
strategy.
• Sometimes helps to deal with the situations
that have a high degree of risk.
• Is linked to the value added business processes.
• Supports the need/ access for/ to the external
data/ databases.
• Is very much result oriented in the nature.

48. Advantages of ESS
• Easy for upper level executive to use
• Enhance personal thinking and decision-
making
• Enhance organizational competitiveness in
the market place
• Better reporting system
• Time management
• Increased communication capacity and
quality

49. Difference between MIS,DSS &ESS
Dimension MIS DSS ESS
Focus Information
processing
Analysis, decision
Support
Status Access
Principal Use Control Planning,
Organizing,
staffing and
control
Tracking and control
Treatment of
Information
Information is
provided to a
diversified
group of users
who then
manipulate it or
summarize
it as needed
Information
provided by the
EIS/or MIS is
used as an
input
to the DSS
Filters and
compresses the
information, tracks
critical data and
information
